Question

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

Answer 1

$163.8

Explanation:

We need to first make the 30% into a decimal. So it will be 0.30.

Then you need to multiply the 0.30 into 126 { 126 x 0.30 }

Which gives you 37.8

Then to fin the original you will need to add the $37.8 to $126

Which is $163.8

Since the discount price was $37.8 and they deducted that from the original price which gave you $126 the question said.

Check : $126 + $37.8 = $163.8

Answer 2

$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
