QUESTION A
The company charges a flat fee (constant fee) of $3.00 and $0.75 per mile (variable fee depending on the number of rides).
If x represents the number of miles and y represents the total cost, the equation relating the two variables, and can be used to find the cost of a taxi ride is given to be:
![y=0.75x+3.00](https://img.qammunity.org/2023/formulas/mathematics/college/n5bvs00qc1vhwbpx3yluu6r8gbpy39we05.png)
QUESTION B
The cost of a taxi ride for 8 miles can be calculated by putting x = 8 in the equation:
![\begin{gathered} y=0.75(8)+3 \\ y=9 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/te408kn5z3mid2ywoq9r3cl2mw9si8hk8o.png)
The cost of the taxi will be $9.00.
QUESTION C
If the ride costs $15, we can calculate the number of miles as follows:
![\begin{gathered} 15=0.75x+3 \\ 0.75x=15-3=12 \\ x=(12)/(0.75) \\ x=16 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/temvh11pq133g2yyzw4ejn8y2t0lj28t8e.png)
The number of miles traveled is 16 miles.
