Question

A pair of diamond earrings has been marked up 50% and is now selling for $198.00. How much were the earrings before the mark-up?

Answer 1

They were 99 dollars before. 

Answer 2

X/198=50/100

multiply 198 by 50
198×50=9900

divide 9900 by 100
9900÷100= 990

add 990 and 198
990+198=1188

the answer is 1188
