Question

For a ride on a rental scooter, Kareem paid a $3 fee to start the scooter plus 11 cents per minute of the ride.The total bill for Kareem ride was $22.69. For how many minutes did Kareem ride the scooter?

Answer 1

Solution:

Given:

$\begin{gathered} Writing\text{ the equation in the form;} \\ y=mx+b \\ \\ where; \\ b=3 \\ m=11cent=0.11 \\ x\text{ is the number of minutes} \\ y=\text{ \ }22.69 \end{gathered}$

Hence,

$\begin{gathered} 22.69=0.11x+3 \\ 22.69-3=0.11x \\ 19.69=0.11x \\ \frac{19.69}{0.11}=x \\ x=179 \end{gathered}$

Therefore, Kareem used 179 minutes to ride the scooter.
