The Schwartz family spent a total of $111.75 for Internet service for 3 months. Each month they received $5.50 as a credit on the bill. Which equation and solution shows

the cost of their monthly Internet service before the credit?

3 (x + 5.50) = 111.75; the monthly Internet service is $31.75

3 (x - 5.50) = 111.75; the monthly Internet service is $42.75

1/3 (x - 5.50) = 111.75; the monthly Internet service is $42.75

1/3 (x + 5.50) = 111.75; the monthly Internet service is $31.75
