Question

The price of a coat increased from $78 to $92. What is the price increase percentage?

Answer 1

18%

Explanation:

Since the original price is $78 then this is the original 100% of the price. The new price will be marked up x percent and be $92. To find the new price set up a proportion with these values:

`(92)/(78)=(x)/(100)`

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

x(78) = 92(100)

78x = 9200

x= 117.9 = 118%

This is 18% more or over the original price.
