2. Destiny rents games from a company that charges a $9.00 monthly fee and $2.50 for each game rental. She ends up paying $26.50
slega [8]

Answer:

x = 7

and it means that 7 games were rented that month

Step-by-step explanation:

Here, we are to solve for x from the given equation

we have this as:

2.5x + 9 = 26.5

2.5x = 26.5-9

2.5x = 17.5

x = 17.5/2.5

x = 7

What x means in this case is that the number of games rented in the month is 7
