Suppose one girl saves $10 every week. Another girl already has $21 and saves $3 every week.

Write and solve an equation to determine when the two girls will have the saved the same amount of money.

So far I have these expression for each girl: one girl has 10w

another girl has 21+3w

Hope someone can help me, thanks.

**drwls**, Monday, December 17, 2007 at 7:30pmYou are off to a good start. Now set

21 + 3w = 10 w

and solve for w.

7w = 21

w = ?
