Answer:
f(10) = 81
This is the cost to get in plus 10 rides
Step-by-step explanation:
The flat fee of 11 is like the y intercept or the cost just to get in with zero rides. The 7 dollars per ride is the slope ( the charge per ride)
We can use y = mx+b
y = 7x+11
f(x) = 7x+11
We want to know how much 10 rides will cost x=10
f(10) = 7*10 +11
= 70+ 11
= 81
This is the cost to get in plus 10 rides
