A website hosting service charges businesses a one-time setup fee of $350 plus d dollars for each month. If a business owner paid $1,010 for the first 12 months, including the setup fee, choose the correct equation and solve to find the cost per month, d.

The correct equation is:

12d + 350 = 1010

Subtracting 350 from both sides, we get:

12d = 660

Dividing both sides by 12, we get:

d = 55

Therefore, the cost per month is $55.

To find the cost per month, d, we can set up the equation as:

12d + 350 = 1010

Because the business owner paid $1,010 for the first 12 months, including the setup fee.

To solve for d, we can follow these steps:

1. Subtract 350 from both sides of the equation:
12d = 660

2. Divide both sides of the equation by 12:
d = 660/12

Simplifying further:
d = 55

Therefore, the cost per month, d, is $55.
