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]
