A watch was on sale for 70% off. The sale price is $60. What was the original price?

$85.71

Step-by-step explanation:

The watch's original price was $85.71

y=p%*x

x=y/p%

x=60/70%

x=60/0.7

x=85.7143

Hope this helps!

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
