Multiply the amount of the discount by pairs of shoes:
21.75 x 7 = 152.25
Add that to the total she spent:
152.25 + 654.50 = 806.75
Divide the total by pairs of shoes:
806.75/7 = $115.25
The answer is C. $115.25

First we find the increase by multiplying the percentage with the base salary
8.70*(6/100)=0.522 that's the increase
then we add it to the base salary
8.70+0.522=9.222$
We have to isolate b using inverse operations.
5a(b - c) = d
Simplify using Distributive Property.
5ab - 5ac = d
Add 5ac to both sides.
5ab = d + 5ac
Divide both sides by 5a.
b = 5ac + d / 5a
Answer:
