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.
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)
Write an algebraic expression to represent
the cost of renting a sleigh for $12 per hour
plus $35.
The equation in slope-intercept form that can be used to calculate the total amount you would pay for using this sailboat is:
y = 20x + 12
In this equation, 'y' represents the total cost of renting the sailboat, 'x' represents the number of hours you would like to rent the sailboat, 20 is the cost per hour, and 12 is the additional cost for life jackets.
To write an equation in slope-intercept form, we need to first understand the equation's components. In this case, the total cost of renting a sailboat is composed of two parts: the hourly rate and the cost of life jackets.
Let's assign the variable 'x' to represent the number of hours the sailboat is rented for. The hourly rate is $20, and the cost of life jackets is a one-time charge of $12.
To calculate the total cost, we multiply the hourly rate by the number of hours (20x) and then add the cost of life jackets ($12).
Therefore, the equation in slope-intercept form to calculate the total amount you would pay for using this sailboat is:
y = 20x + 12
In this equation, 'y' represents the total cost and 'x' represents the number of hours the sailboat is rented for. The slope of the equation (20) represents the hourly rate, and the y-intercept (12) represents the cost of life jackets.
