Answer:
[tex]58x-54=468[/tex]
Step-by-step explanation:
Number of repeat customers = 40
Amount charged from each of the repeat customers = $ x
So,
amount charged from 40 customers = $ 40 x
Number of new customers = 18
As Michel charged each of the new subscribers $3 less than the amount charged from each of the repeat customers,
amount charged from each of the new customers = $ (x - 3)
So,
amount charged from 18 new customers = $ 18(x - 3)
Total amount charged from repeat and new customers = [tex]\$[(40x)+18(x-3)]=\$40x+18x-54=\$58x-54[/tex]
As Michel collected $468 for delivering newspapers,
