Gregory and 3 of his friends decided to go bowling, but did not know where to go. When they search info at different bowling alleys, Alley A charged $3 per game plus $5 for shoes. Alley B charges $5 per game plus $2 for shoes. Note that all 4 of them would need to rent shoes.
Set up an equation that shows when the total cost for all 4 of them bowling at Alley A is equal to the total cost of them bowling at Alley B. No need to solve the equation.
4(3x+5)=4(5x+2)
Solve for x:
13<=5x-12<18
