Answer:

4 weeks

$28

Step-by-step explanation:

Let

x = number of weeks

Jamal's savings = 18 + 5x

Samuel's savings = 10 + 7x

Equate both savings

Jamal's savings = Samuel's savings

18 + 5x = 10 + 7x

18 - 10 = 7x - 5x

8 = 2x

x = 8 / 2

= 4

x = 4 weeks

Check:

18 + 5x

18 + 5(2)

18 + 10

= $28

Each boy would have saved an equal amount of $28 at the end of the 4th week
