A CPA gets paid $160 for each tax return he prepares, and his goal is to earn $6240 preparing tax returns during this tax season. If he has already prepared 4 tax returns this tax season, how many more tax returns must he prepare in order to reach his goa
The equation that defines his pay is PAY= 160n where n = number of returns
he has already earned 160 x 4 = 640 dollars
so 6240 - 640 = amount still to be earned = 160n
5600=160n
n=35 more returns to prepare
