Answer to problem of the week January 17th

The four boys must raise $4,000 for them to each have $1,000 at the end of the summer.  In addition, they must cover their expenses at $152.00 a month for four months.  That comes out to $608.  Alltogether, they must make $4,608 to reach their goal.  If you divide that amount by $256.00 (the amount made from one house) you will get 18 which is the number of houses they boys must paint to reach their goal.

Answer to Zoe's Border

Since the length of Zoe’s blanket is 6 yards, the width is 2, because 2x3=6.  You can use an equation to solve for the width:

Length=3 x width

6=3w

6=3(2)

Since the width is 2 yards and the length is 6 yards, we use our perimeter formula to find the distance around the blanket:

(2xlength)+(2xwidth)=perimeter

(2x6) + (2x2)= p

12+4=P

P=16 yards

Since Zoe is putting border around both sides of the blanket, we must multiply the perimeter by two to get 32 yards, so:

Length=6 yards

Width = 2 yards

Perimeter= 16  yards

Total Ribbon Needed= 32 yards

Problem of the Week January 4th: Zoe's Border

Zoe is putting a border around her blanket and she needs to know how much ribbon to buy.  The lenth of the blanket is three times the width of the blanket.  If the length of the blanket is 6 yards, what is the width of the blanket?  What is the perimeter of the blanket?  How much ribbon does she need to buy total for her border if she wants to put it on both sides of the blanket? 

Solve and explain how you got your answer.  You must solve for the width, perimeter, and total amount of ribbon needed. 

You will have until Friday afternoon at 5pm to post your answer!
