A car rental company charges a flat fee of $50 plus $20 for each day the car is rented. If a customer rents a car for x days, write the equation for the total cost and identify the constant coefficient.
C = 50 + 20x; constant coefficient = 50
C = 50 + 10x; constant coefficient = 10
C = 50 + 20x; constant coefficient = 20
C = 30 + 20x; constant coefficient = 30

A bakery sells cupcakes for $3 each and has a daily overhead cost of $50. Write an equation for the total revenue generated from selling x cupcakes and identify the constant coefficient.
R = 3x - 50; constant coefficient = -50
R = 3x; constant coefficient = 0
R = 50 + 3x; constant coefficient = 50
R = 3x + 50; constant coefficient = 3

A phone plan costs $25 per month plus $0.10 for each minute used. If a customer uses m minutes in a month, write the equation for the total bill and identify the constant coefficient.
Total Bill = 25 + 0.05 * m; Constant Coefficient = 25
Total Bill = 25 + 0.10 * m; Constant Coefficient = 25
Total Bill = 25 * m + 0.10; Constant Coefficient = 0.10
Total Bill = 0.10 + 25 * m; Constant Coefficient = 0.10

A delivery service charges a base fee of $15 plus $5 for each package delivered. If a customer has p packages to deliver, express the total cost as an equation and identify the constant coefficient.
C = 10 + 5p; constant coefficient is 10.
C = 20 + 5p; constant coefficient is 20.
C = 15 + 10p; constant coefficient is 15.
C = 15 + 5p; constant coefficient is 15.

A school charges a registration fee of $100 plus $15 for each class taken. If a student enrolls in c classes, write the equation for the total cost and identify the constant coefficient.
Total Cost = 100 + 20c; Constant coefficient = 100
Total Cost = 150 + 15c; Constant coefficient = 150
Total Cost = 100 + 15c; Constant coefficient = 100
Total Cost = 100 + 10c; Constant coefficient = 10

A landscaping company charges a flat rate of $200 for a service plus $50 for each additional hour worked. If the service takes h hours, express the total cost as an equation and identify the constant coefficient.
Total Cost = 200 + 50h; Constant coefficient = 200
Total Cost = 200h + 50; Constant coefficient = 50
Total Cost = 200 + 75h; Constant coefficient = 200
Total Cost = 150 + 50h; Constant coefficient = 150
