Find the cost c for 18 rides.

Answer 1

We want to know the cost for 7 rides and for 10 rides. We see that for each ride the price increases by $3.50. And thus the price for 7 rides will be:

`29.00+3.50=32.50`

And the price for 10 rides will be:

`36.00+3.50+3.50=39.50+3.50=43.00`

Now, for finding the equation we use that the state fair charges $8 for a general admission, and $3.50 for each ride. This can be written as:

`y=8+3.50x`

where x represents the number of rides.

For example, if we want to know the cost for 18 rides, we replace the value of x by 18, and we get:

`\begin{gathered} y=8+3.50(18) \\ =8+63 \\ =71 \end{gathered}`

Then, the cost for 18 rides is $71.
