mezya [45]
The have been saving for 10 weeks.

Given:
Duane = $5 every other week. meaning every 2 weeks
Mick = $2 every week
Amount Saved = $45

First, divide Duane's $5 by 2 to get his weekly contribution.
$5/2 = $2.50

let x be the number of weeks.

Duane + Mick = $45
2.50x + 2x = 45
4.50x = 45
4.50x/4.50 = 45/4.50
x = 10 weeks

to check:
2.50x + 2x = 45
2.50(10) + 2(10) = 45
25 + 20 = 45
45 = 45
