Elenna [48]

The difference in price per passenger for a group of 16 versus a group of 10 is $26.25

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more number and variables.

From the graph:

The cost for a group of 16 friends is $2500, while for a group of 10 friends is $1300.

Cost per passenger for 16 friend = $2500 / 16 = $156.25

Cost per passenger for 10 friend = $1300 / 10 = $130

The difference in price = $156.25 - $130 = $26.25

The difference in price per passenger for a group of 16 versus a group of 10 is $26.25

6) Parking lot A charges $19.00 to enter the parking lot plus $1.50 per hour
Olegator [25]

Answer:

4 Hours.

Step-by-step explanation:

You would set this up as an equality where x represent hours

19.00 + 1.50x = 14+2.75x

You then get the x on one side by subtracting 14 from both sides and 1.50x from both sides.

5 = 1.25x

Divide both sides by 1.25 to x by itself.

4 = x
