Answer:

The camera's regular price was #$790#.

Explanation:

We can express discount amount as #x# and the original price of the camera as #x+632#. The equation to determine the price will be:

#(x+632)xx20/100=x#

Simplify.

#(x+632)xx(1cancel(20))/(5cancel(100))=x#

Multiply both sides by #5#.

#x+632=5x#

Subtract #x# from both sides.

#632=4x#

Divide both sides by #4#.

#158=x#

Since the discount amount #(x)# is #158#, the original price #(x+632)# will be #(158+632)=790#.
