Abby owns her own sports shop. She buys football jerseys for $20 each and sells them for $45 each. What is the percent markup of each jersey?
A. Write an algebraic equation for the problem?
B. Solve your equation and label your answer.
let p mean the percent of markup
45 = 20 (1 + p) the final cost is 45, to get it you multiply 100 percent or (1) of 20 plus some percent
45 = 20 + 20p distribute the 20
25 = 20p subtract 20 from both sides
25/20 = p divide by 20 on both sides
5/4 = p reduce by 5
1.25 = p or the markup is 125%
