Question 9 of 2
vagabundo [1.1K]

Company A charges a $125 annual fee plus $7 per hour car share fee.

Company B charges $110 plus $10 per hour. The minimum number of hours that a car share needs to be used per year to make company A a better deal is 6 hours.

A: y=125+7 x

B: y=110+10 x

for A to be a better deal than B, 125+7 x<110+10 x has to be true

subtract 7x from both sides and subtract 110 from both sides of the inequality: 15<3 x

divide by 3: 5<x

so x has to be greater than 5 , im pretty sure it's 6 hours but it might also be 5 depending on how it's taught for you.

Equations are not always balanced on both sides using a "equal to" symbol in mathematics. Sometimes it can be about a "not equal to" relationship, meaning that something is superior to or inferior to another. In mathematics, an inequality is a relationship between two numbers or other mathematical expressions that results in an unequal comparison. Inequalities are the name given to certain algebraic mathematical expressions.
