Question

Fu times Amusement Park charges a $7 admission fee plus $1.75 per ride. What is the equation, in intercept form for calculating the total cost, C, of going to the park and riding r rides.

Answer 1

A linear equation in slope-intercept form is represented by the expression:

$\begin{gathered} C=mr+b \\ \text{where,} \\ m=\text{ rate of change (\ 1.75 per ride)} \\ b=\text{ y-intercept (initial value, means admission fee)} \end{gathered}$

Then, the equation that represent this situation would be:

$C=1.75r+7$
