Question

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

Answer 1

Answer:

$180

Step-by-step 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:

$\frac{126}{x}=\frac{70}{100}$

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

x(70) = 126(100)

70x = 12600

x= $180
