Answer:
18%
Step-by-step 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:
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.
