the price of salmon at a fish market is 5.40 per pound. this is 150% of its cost at a supermarket. how much does it cost at a supermarket?

$8.10 because half of 5.40 is 2.70 so just add it too 5.40 and there is your answer

$3.6

Step-by-step explanation:

x=price of fish at the supermarket

Since the fish market has a 50% mark-up, 5.40 is 150% of x.

all you have to do is divide this price by 15 to get the price of the fish at the supermarket.

54/15=3.6

$3.6 is the final answer.

Hope this helped!
