The cost of renting a sailboat at a lake is $20 per hour plus $12 for life jackets. Write an equation in slope-intercept form that can be used to calculate the total amount you would pay for using this sailboat.

Answer 1

y=20x+12

if x=number of hours rented
example I want to rent the sailboat for 3 hours. The life jacket is a fixed number and doesnt change, so we just tack that on the the end of the equation.

Y= total amount spent

y=20(3)+12
y=72 (you spent 72 dollars for 3 hours on the boat)

Answer 2

Write an algebraic expression to represent
the cost of renting a sleigh for $12 per hour
plus $35.
