Answer:
9.06, or real explanation.
Step-by-step explanation:
<em>"Marco buys a certain brand of shampoo for a supplier $7.25 per bottle he sells it to his customers at a makeup 25% what would the makeup be"</em>
I am going to assume makeup is supposed to be markup, but I will answer all there is.
To find how much higher he charges people for the shampoo, we can multiply the original cost by the percent of increase, so in our case 7.25*.25
7.25*.25=1.8125, or $1.81
1.8125 is the total extra he charges people for the soap.
NOW FOR THE TOTAL COST-------------------
For the total cost we take the original + the added cost
1.8125+7.25=9.0625, or 9.06
