Accepted Solution

A:

Answer:[tex]y=80x+25[/tex]Step-by-step explanation:Letx ----> the number of hoursy ---> the total cost of renting a jet ski in dollarswe know thatThe linear equation in slope intercept form is equal to[tex]y=mx+b[/tex]wherem is the slope or unit rate of the linear equationb is the y-intercept or initial valueIn this problem we haveThe 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 skisubstitute[tex]y=80x+25[/tex]
