Problema Solution
. Dylan's Bicycle Shop offers a new bicycle on sale for $259.92 after a 10% markdown. What was the cost of the bicycle to Dylan if the markup was 30% based on the cost? (Round to the nearest cent.)
Answer provided by our tutors
let x be the original price (cost)
x - 0.10x = 259.92
by solving we find
x = $288.8
the markup was 30% based on the cost
0.30*288.8 + 288.8 = 1.30*288.8 = $357.44
the cost of the bicycle was $357.44.
