The cost of their monthly Internet service before the credit is $31.75

The required equation = 3(x+5.50)=111.75

Step-by-step explanation:

Let the monthly cost be x

Each month they received $5.50 as a credit on the bill.

The Schwartz family spent a total of $111.75 for Internet service for 3 months.

So, total cost of three moths = 3(x+5.50)

Since we are given that The Schwartz family spent a total of $111.75

So, 3(x+5.50)=111.75

$x+5.50=\frac{111.75}{3}$

x+5.50=37.25

x=37.25-5.50

x=31.75

Hence the cost of their monthly Internet service before the credit is $31.75

The required equation = 3(x+5.50)=111.75
