Answer by ReadingBoosters(3246) (Show Source): You can put this solution on YOUR website!
s = 126 + 16.50w
where s is savings and w is number of weeks
...
If s is 500, find w
500 = 126 + 16.50w
...
Isolate the variable
16.50w = 500 - 126
16.50w = 374
Divide both sides by 16.5
w = 22.6, which is weeks
