At an amusement park, a person spends $30 on admission and food, and then goes on r number of rides that cost $2 each and can go up to 5 ride

Answer 1

We can write an equation, but we don't have enough info in your question to solve.

30 = A + F + 2r

plus, an inequality 0<= r <= 5 (this is if you can have any number of rides including 0 and 5)

if they must go for at least one ride, then 1 <= r <= 5

where A = price of Admission, F = spent on Food, r = number of rides

I think all we can say is that 20 <= A + F <= 30

this with 0 rides allowed, you can figure out how it changes if 1 is the minimum.
