Flora paid her supplier $0.75 a stem for roses to sell at her flower shop. She added an 80% markup. What is the amount of markup?

$0.60

Step-by-step explanation:

the question ask us to find the amount of the markup on Flora’s roses. The amount of markup is given by:

markup rate x original price = amount of markup

the markup rate is in decimal form

since the original price was $0.05 and the markup price is 80% = 0.80, we have

0.80 x .075 = 0.60

thus, the amount of the markup on Flora’s roses was $0.60
