Answer:
There are two limo companies that charge based on the number of people, x, that they carry. Limo A charges $30 plus $4 per person. Limo B charges $70 plus $2 per person. How many people can ride to make the two companies charge the same amount?
Step-by-step explanation:
The correct situation is the third one, this is because the expression we have is:
let's take the left side as the charge of the company limo A, and the left side as the charge of limo B.
Since 'x' is the number of people, the left side tells us that limo A charges $4 per person (hence the 4x) and adds an additional $30 (hence the 30 added on the left side).
And the right side tells us that limo B charges $2 per person (hence the 2x) and adds an additional $70 (hence the 70 added on the right side).
And since we have an equal sign this means that the expression represents the number of people that can ride and will pay an equal amount in each company.
This is the situation that the third option describes:
There are two limo companies that charge based on the number of people, x, that they carry. Limo A charges $30 plus $4 per person. Limo B charges $70 plus $2 per person. How many people can ride to make the two companies charge the same amount?
