Answer 1

Answer:

30 Weeks

Step-by-step explanation:

No. of dollars I am saving = $7

No. of dollars my sister is saving = $5

How long will it be before you and your sister have the same amount of money =?

60 + 7$x$ = 120 + 5$x$

7x - 5x = 120 - 60

2x = 60

x = 60/2

x = 30

60 + 7 x 30 = 270

120 + 5 x 30 = 270
