A pizzeria charges $12 per pizza plus an additional $3 for delivery. Which equation represents the cost of having any number of pizzas delivered?

• c = 12p + 3

• c = 12p

• c = 3p

• c = 12 + 3p

Patrick earns $20 for every lawn that he mows. Write an equation used to find t, the total amount of money he earns from mowing n lawns.

• n = 20t

• t = 20n

• t = n + 20

• t = n - 20
