Question

an amusement park charges a flat fee of $11, plus $7 per ride. create a liner function to represent this situation the find f(10) for the function and explain what it means

Answer 1

f(10) = 81

This is the cost to get in plus 10 rides

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
