if $15 is- 100 % then
$12 - x
X=(12*100)/15
X= 80
so 100%-80% = 20 % savings

Well you paid $12 dollars out of $15 so 12/15. That equals 0.8 of the total. so You paid 80% of the total, meaning you saved 20%.

for this you have an original price of 15 times some percentage that you pay equal to the amount you are paying. so your equation is 15 * x =12
you then solve for x to find the percentage you are paying 80% since x = .8
so if you are paying 80% then you are saving 20%
