Question

Ryan invited 5 of his friends to the local fair and paying $5 for everyone. The admission to enter is $5 per person. Ride tickets are 75 c (cent) per ticket. what is the maximum number of ride tickets he can purchase is he has $50? define the variable

Answer 1

50-5(6)=30 = .75r

r = 30/.75 = 3000/75 = 120/3 = 40

= 40 rides max on a $50 budget

with 6 people (5 friends + himself), that's 6 rides each for 2 and 7 rides each for 4
