Question

At the amusement park, Laura paid $6.00 for a small cotton candy. Her older brother works at the park, and he told

her they mark up the cotton candy by 300%. Laura does not think that is mathematically possible. Is it possible,
and if so, what is the price of the cotton candy before the markup?

Answer 1

Yes it is possible,

6 = 300% × W

6 = 3.00 x W

6/3 = W

2 = W

W : 2, which means that before the markup the cotton candy costs $2.00

Answer 2

yes

The price of marked up candy is $6.00

perentage of mark up is 300%

let the marked up amount be represented as x

let 300% mark up be represented as 3x

the equatiopn for finding the price before markup

can be represented as 3x-x=$6.

2x=$6

x=$3.
