Answer:
$350
Step-by-step explanation:
if the sale is 30% we have to find what is 30% of 500 so we can subtracted from what we pay .
line up what you know:
$500 represents 100%
$x represents 30 %
cross multiply
x*100 = 500* 30 ; divide both sides by 100
x= 500*30 /100 = 150
the sale price is 500-150= $350
