Respuesta :
Original price be x
Discount price be y
The equation is
- y=x-5
So
- y=3(x-5)
- 60=3x-15
- 3x=75
- x=25$
Answer:
3(f - 5) = 60
$25
Step-by-step explanation:
Let f = full price of rash-guard
Given:
- during the sale, rash-guards sell for $5 less than full price
- cost of 3 rash-guards during sale is $60
Therefore, the equation you can use to find how much money each rash-guard costs at full price is:
3(f - 5) = 60
To calculate the full price of the rash-guard, solve the equation for f:
⇒ 3(f - 5) = 60
Expand:
⇒ 3f - 15 = 60
Add 15 to both sides:
⇒ 3f = 75
Divide both sides by 3:
⇒ f = 25
Therefore, the full price of each rash-guard is $25.
