Question

Ramona has $8.00 in her savings account and adds $1.00 each week. Claire has $12.00 in her savings account and adds $3.00 each week. After how many weeks will Claire's account have twice as much money as Ramona's?

Answer 1

After 2 weeks Ramona will have twice as much as Claire.

work

claire 8$

8*2=16

12*2=24

Answer 2

To find the answer, we have to set up an equation:

Let the weeks be x.

The amount Ramona has after x week:8+1(x)

The amount Claire has after x week:12+3(x) or 2[8+1(x)], as written in the question above.

12+3(x) = 2[8+1(x)]

12+3x = 16+2x

3x-2x = 16-12

x = 4

Therefore, the answer is 4 weeks.

Hope it helps!
