Fixed fare of hiring an Uber is $12, the fare for every additional mile is $5 per mile.
Set up an inequality to show how much a person can travel with $50 or less. Represent the additional mile by m.
12 + 5m ≤ 50
What is a system of equations?
Two equations
What is the run when slope is -3/8? What direction do you go?
Run = 8 to the right
Isolate the y when the equation is 4x+2y > 18
y > 9 - 2x
A delivery service charges a flat fee of $3.50, plus an additional $1.20 per mile for deliveries. If David has at most $25 to spend on delivery charges, how far could he have his package delivered?
Write the inequality that represents this situation and solve it to find the maximum distance David can afford to have his package delivered.
3.50 + 1.20m ≤ 25
m = 17.9 or 18
