The cost to rent a jet ski is $80 per hour. in addition there also includes fee for a lesson on how to use the jet ski. Steve rented a jet ski for 3 hours and the total bill was $265. Write the equation for the total cost of renting a jet ski y for x hours.

Respuesta :

Answer:

[tex]y=80x+25[/tex]

Step-by-step explanation:

Let

x ----> the number of hours

y ---> the total cost of renting a jet ski in dollars

we know that

The linear equation in slope intercept form is equal to

[tex]y=mx+b[/tex]

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value

In this problem we have

The slope is equal to

[tex]m=\$80\ per\ hour[/tex]

we have the ordered pair (3,265)

substitute in the linear equation

[tex]265=80(3)+b[/tex]

solve for b

[tex]265=240+b[/tex]

[tex]b=265-240[/tex]

[tex]b=\$25[/tex] ----> fee for a lesson on how to use the jet ski

substitute

[tex]y=80x+25[/tex]
