Question

A telescope costs $126 with a 30% discount. What was the original price?

Answer 1

$180

Explanation:

Since the cost of the telescope with the 30% discount is $126 then $126 is 70% of the original price. Remember 100-30=70. To find the original price set up a proportion with these values:

`(126)/(x)=(70)/(100)`

Solve for the original price by cross multiplying numerator with denominator.

x(70) = 126(100)

70x = 12600

x= $180
