Answer 1

Answer:

28 weeks

Step-by-step explanation:

First, find how much her total savings was. Since $42 is one third of the total, the total is 3(42), which is $126. Now divide by her weekly allowance to find the number of weeks she saved. 126/4.5 = 28.

Answer 2

Jennifer has been saving for 28 weeks.

First find out the total amount that Jennifer has saved. Assume that total is y:

1/3 x y = 42

1/3y = 42

y = 42 ÷ 1/3

y = $126

If Jennifer was saving at a rate of $4.50 per week, the number of weeks she has been saving is:

= Total amount saved / savings rate

= 126 / 4.50

= 28 weeks

Jennifer has been saving for 28 weeks
