Answer 1

3(x+5.50)=111.75 .       $31.75

Answer 2

Answer:

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 =  $3(x+5.50)=111.75$
