After 4 weeks, Macy and Robby will have same amount in their accounts.

Step-by-step explanation:

Given,

Amount saved by Macy each week = $12.50

Let,

x be the number of weeks.

M(x) = 12.50x

Amount saved by Robby each week = $7.50

Amount Robby already have = $20

R(x) = 7.50x + 20

For same amount;

M(x) = R(x)

Dividing both sides by 5

After 4 weeks, Macy and Robby will have same amount in their accounts.

Keywords: function, division

Macy: 0 + 12.50x

Robby: 20 + 7.50x

After 4 weeks, they will have the same amount of money. (Both will have $50 by then)
