Ronald went bowling with his friends. He paid $9 to rent shoes, but has a coupon for $3 dollars off the shoes(combine like terms). He paid $9.50 for each game of bowling. If she spent a total of $84, then how many games did Ronald bowl?

Step-by-step explanation:

Let x represent the number of games that Ronald bowled.

He went for bowling with his friends and paid $9 to rent shoes, but has a coupon for $3 dollars off the shoes. It means that the amount he paid to rent the shoes is

9 - 3 = $6

He paid $9.50 for each game of bowling. It means that the total amount she would pay for x games is

9.5x + 6

If she spent a total of $84, it means that

9.5x + 6 = 84

9.5x = 84 - 6

9.5x = 78

x = 78/9.5

x = 8.2

Since the number of games cannot be a fraction, then

Ronald bowled 8 games

the answer is 99.
