Question

at the amusement prak, laura paid $6 for a small cotton candy her older brother works at the park, and he told her they mark up the cotton candy candy by 300% what is the price of the cotton candy before the markup

Answer 1

Hi Lisa,

 

Let's say the original price of the cotton candy is "C"

Then we have the original price, C plus 300% of C being equal to the new $6 price.

 

C + 3C = 6

 

4C = 6

C = 6/4

C = $1.50
