8.95 x 8 = $71.60 +12.07 = $83.67 + 6.28 =89.95




Final ans.-89.95

Kendrick F-Centanni said...

Sam spent $71.60 for the baseball caps. Then, the total for the caps&tax was $83.67. If he had $6.28 left, therefore he must have started with $89.95, or rounded to $90.

I got $89.95 cents for my answer

Yutaka T-Centanni said...

Sam had $89.95 because 8 ball caps for $8.95 each equals $71.60. then I added $12.07 (sales tax) $19.67 and got $83.67. Finally, I added the money left ($6.28) to get my final answer 89.95.

she started out with $89.95

Georgia V- Buckalew said...

My answer was $89.95

I first wrote down all of the information that I needed. Then I added $8.95 eight times and I got $71.60. After I did that I added $12.07 (sales tax) to the $71.60 and I got $83.67. Last I added the $6.28 to my $83.67 and the $6.28 equals the amount Sam had left over after she paid for everything including the sales tax.

Sam had 89 dollars and 95 cents when she entered the store. First you multiply 8 dollars and 95 cents by 8 friends and you get 72 dollars and 60 cents. Then you add 72 dollars and 60 cents to 12 dollars and 7 cents and you get 83 dollars and 67 cents. Then for the final step you add 83 dollars and 67 cents to 6 dollars and 28 cents and you get the total of 89 dollars and 95 cents.

I started with $12.07+$6.28=$18.35
but it is $18.35 FOR EACH BALL CAP.
So I did $18.35x8 wich = the final answer $146.80......

JohannahV-Buckalew said...

FIRST you do $8.95 each * 8 ball caps and you get $71.60 then you add $12.07 and you get $83.67 then you do $83.67-$6.28 and you get $77.39 as your answer.

ellen l.-centanni said...

Sam started with $82.95.

CollinM.-Centanni said...

The answer is $89.95. Because when I found the total amount spent , I added the amount that she left with to find out how much money she had at the start.

JimmyS.Buckalew said...

This is how I got the answer:

I mutipled $8.95 by 8 (her 8 friends) and the answer I got $71.60. Since the cashier charged $12.07 more in sales tax, I added that to $71.60 and got $83.67. I added what she had left (which was $6.28) to $83.67 which the final answer is $89.95

Emma s. Miss Buckalew. said...

I think the answer is $89.95 because if you take
$8.95x8=$71.06 + $12.07 = $89.95

Justin J.-Centanni said...

Sam started with $89.95, he used $83.67 (including tax) and then had $6.28.

JasmineJ-Buckalew said...

The total cost of the ball caps were $73.60. Plus tax it was a total of $85.67. And Sam started with $91.95.

GeraldineB-Buckalew said...

1.First I did 8.95 times 8 or add it 8 times and I got 71.60.

anwser was 89.95.

Katie C.- Centanni said...

She started with $89.95, because she bought 8 ball caps, for $8.95 each. i f you do 8 and multiply it by $8.95, then you get $71.60. Add the tax, and you get $83.67. Finally you add the amount she had left ,$6.28, and you get a final total of... $89.95!!!!!

Michelle J.-Centanni said...

sam stared $89.95.because if you do $8.95- each for the ball caps

$71.60- total of ball caps
+$12.07- sale tax
-------
$83.67- total of ball caps and sale
+$ 6.28- measely tax
--------
$89.95- final answer.

Zen.K-Buckalew said...

.$8.95x8
.and then you add the tax(12.07)and the money he had left.

.He started out with $89.95

ClaireG said...

What I did on my piece of paper is I added $8.95 8 times and got $71.50. I then added the tax and it changed to 73.57. Next I added the money she left the store with and got 79.85 dollars. So thats how much Sam spent.

SamC-Centanni said...

First I will round $8.95 to $9.00. Next I will multiply 9.00 by 8. Then I will multiply .05 by 8 to subtract what I rounded. Then I will add the tax to my answer. Finally I will add the money Sam had left over to get my final answer.

9x8=72, 8x.05=.40, 72.00-.40=$71.60
$71.60
+12.07
=83.67
+6.28
=$89.95

Lucia L-Centanni said...

$8.95 x 8 = $71.60

$71.60 + $12.07 = $83.67

$83.67 + $6.28 = $89.95

The answer is $89.95

8.95 each. + 71.60
12.07 tax 1 89.95dollars
12.07
+ 6.28

x 8
71.60

vallen - centannni said...

Sam started out with 81.94 dollars. Because you multiply
8.95X8 friends.Then you multiply 3.02(tax)8 times per.ball.then you add 6.28(change)

David.T said...

89.95 cause she bought 8 of them they were 8.95 each and 8.95 x 8 equals 71.60 + 12.07 in tax is 83.67 + her total which equals 89.95

Kara H Centanni said...

each cap costs 8.95 and sam bought 8. there are 2 ways you can do this part you can add 8.95 together 8 times or you can do 8.95 x 8 both equal 71.60. add 12.07 which is tax and get 83.67 then add 6.28 because thats how much she had at the end so add it to 83.67 and get 89.95 which is how much she started with.

MichaelB-Buckalew said...

She had $89.95. I multiplied $8.95 by 8, then added $12.07 and $6.28 to all of that.

JoshB-Buckalew said...

I think she started with 81.18.




I got this answer by multiplying.

Ashley-K centanni said said...

the answer is 85.30 because
8.95
x 8
-----
71.60
but an Additional 12.70 as task
witch equal 85.30

TylerM.-Miss Young said...

Sam spent 71.60 not including tax, but with the 12.07 tax it ended up being 83.67. then since he had 6.28 left he must have started with 77.39
