shutvik [7]

After 10 weeks, the boys will have same amount in savings.

Step-by-step explanation:

Given,

Roberto already have $30.

Amount saved each week = $5

Let,

x be the number of weeks.

R(x) = 30+5x

Amount saved by Jack each week = $8

J(x) = 8x

For same amount, the functions will be equal.

R(x) = J(x)

30+5x=8x\\30=8x-5x\\30=3x\\3x=30

Dividing both sides by 3

\frac{3x}{3}=\frac{30}{3}\\x=10

After 10 weeks, the boys will have same amount in savings.
