Answer:
The new price is 42.50
Step-by-step explanation:
First find the discount
50 *15%
50 *.15
7.5
Subtract this from the original price
50-7.5
42.50
The new price is 42.50
Divide by 5, if question is a multiplication
But, multiply by 5 if question is based on division.
So, you're basically doing the inverse, of the operations you've been given.
For example:
x/5 = 2
x5 ( Multiply by 5)
x = 10
3 x y = 12
÷3
y = 4
Hope this helps!
