The number of miles in the ride is 4
What are linear equations?
Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
How to determine the solution to the system?
A system of linear equations is a collection of at least two linear equations.
In this case, the given parameters are:
Pick up fee = $4.70 per ride
Rate = $2.50 per mile
Let the number of miles be x and the total amount of fare be y
So, we have:
y = Pick up fee + rate * x
This gives
y = 4.70 + 2.5x
The total fare was $14.70, not including the tip
This gives
4.70 + 2.5x = 14.70
Subtract 4.70 from both sides
2.5x = 10.0
Divide both sides by 2.5
x = 4
Hence, the number of miles in the ride is 4
