Harry purchased 16 hinges for his kitchen project. they were each on sale for $3 off the regular price.

the total cost of the hinges was $80.

what was the regular price for each hinge?

THE ANSWER IS 8 DOLLARS BCUZ 80/16 EQUALS 5, AND 5+3 EQUALS 8

$80 for 16 hinges.  Divide 80 by 16 to find out how much was paid for each one.

80 divided by 16 = 5.

So you paid $5 each. 

If the original price was $3 more, then add 5 + 3 = 8.

$8 each.
