Answer: D) 10 jerseys

Step-by-step explanation:

Let j represent the number of jerseys and C for total cost

Local company eqn: C = 5.25j + 45

Online company eqn: C = 7.75j + 20

Set both sides equal to solve:

5.25j + 45 = 7.75j + 20

5.25j - 7.75j = 20 -45

- 2.5j = -25

\frac{-2.5j}{-2.5}=\frac{-25}{-2.5}

j = 10

Therefore, the cost is the same for both companies when 10 jerseys are sold
