Question

Steven saves $0.30 each week.

Answer 1

after 4 weeks:

.3*4= 1.2 saved

then it is doubled

1.2*2 = 2.40

8 weeks

he will have saved for 4 more weeks ( week 5 6 7 8)

4 * .3 = 1.2 saved

2.4 + 1.2 = 3.6 saved

then it is doubled

3.6 * 2 =7.20

he will have saved for 4 more weeks ( week 9, 10, 11, 12)

4 * .3 = 1.2 saved

7.2+ 1.20=8.40

then it is doubled

8.4*2 = 16.8

He will have 16.80 after 12 weeks
