Answer:
The answer is that Libby bowled 6 games.
Explanation:
From the information given, the total cost of going bowling during a holiday special would be equal to the special cost for pizza, bowling shoes, and unlimited drinks plus the result of multiplying the cost per game for the number of games for the number of people, which is:
c=40+(2*6*x)
c=40+12x, where:
c is the total cost of going bowling
x is the number of games
Now, you can replace the total cost with 112 and solve for x:
112=40+12x
112-40=12x
72=12x
x=72/12=6
According to this, the answer is that Libby bowled 6 games.
