Question

How much would a taxi ride for 8 miles cost

Answer 1

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`

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}`

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}`

The number of miles traveled is 16 miles.
