Question

Blue Tide Swim Shop is having its annual summer sale, when every item in the store gets marked down. During the sale, rashguards sell for $5 less than full price. Miguel purchases 3 rashguards and pays a total of $60.

Which equation can you use to find how much money, f, each rashguard costs at full price?
3(f-5)=60
5f-3=60
3f-5=60
5(f-3)=60
How much does each rashguard cost at full price?
$

Answer 1

3 (f - 5) = 60 , $25 / each

Explanation:

f = full price of each rashguard

Miguel purchases 3 rashguards for $60

The price Miguel paid:

(Full price - $5) * 3 = $60

We can rewrite this as the equation:

3 (f - 5) = 60 (first equation)

How much does each rashguard cost at full price?

Solve for f to find the full price

3(f - 5) = 60

Divide both sides by 3

f - 5 = 20

f = 25

The full price of each rashguard is $25
