Answer:
80%
Step-by-step explanation:
Original price =$75.00
Sale price =$60.00
The percentage discount can be calculated by dividing the sale price by the original price multiplied by 100%.
So % discount = $60.00/$75.00 x 100%
0.8 x 100%
80%
Janelle got the dress on a discount of 80%.
This is so because she got the dress for a price less than the original price
If you plug in the x and y of choice b you would see that it does not equal 18.
6(3) + 3(-1) = 18
18 + (-3) = 15
