Tyrone saved 24$ of the 60 that he earned mowing lawns .what percent of his earnings did tyrone save
mezya [45]
If 24 of the 60 were saved then the percent saved is

(24/60) x 100

Let's imagine for a second that all 60 was saved, then 100% of the money would be saved. Which makes sense, because

(60/60) x 100 = 100%

So the amount saved dived by the amount earned all times 100 is the percent saved.

We need 6.5% to a decimal so..
6.5% /100 = 0.065

$21.30 X 0.065 = 1.3845 tax on the shirt
 
So.. we add the price of the shirt, and the amount of tax on the shirt
$21.30 + 1.3845 = $22.6845

Answer = $22.68
