Answer :
Jane : y = 0.10x + 5...or f(x) = 0.10x + 5
Joe : y = 0.20x + 4...or f(x) = 0.20x + 4
Joe : y = 0.20x + 4...or f(x) = 0.20x + 4
The linear equations to calculate the earning by Jane and Joe's Uber business per ride, given the initial fee and charge per mile:
Jane: y = 5 + 0.1x
Joe: y = 4 + 0.2x
What is a linear equation ?
A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.
For Jane's Uber business, she charges $5 initial fee and $0.10 a mile.
Let Jane's earning from a ride be $y.
Let the number of miles she drove in that ride be x miles.
Linear equation to calculate the earning from a ride given the number of miles rode: y = 5 + 0.1x
For Joe's Uber business, he charges $4 initial fee and $0.20 a mile.
Let Joe's earning from a ride be $y.
Let the number of miles he drove in that ride be x miles.
