Answer:
The revenue would be $ 440
Step-by-step explanation:
Consider the correct complete question is,
"Roundup Rackets restrings a tennis racket for $22. If the store restrings 20 rackets each month, what is the monthly revenue from restringing rackets."
Thus,
The price for restrings each tennis racket = $ 22,
Number of rackets re stringed in a month = 20,
Hence, the monthly revenue = price of restrings each tennis racket × number of rackets re stringed
= 22 × 20
= $ 440
Answer:
The solution of a system of linear equations is:
D. The values of the variables that satisfy both equations.

4x + 2x = 30 + 24
6x = 54
x = 9
answer: the number is 9
