Step-by-step explanation:
Write an equation.
c= the cost
p= the number of pizzas
8p means $8 per pizza
And adding 3 includes the delivery charge.
c=8p+3
Plug in the numbers 1-4.
1: $11
2: $19
3: $26
4: $35
This equation is NOT a direct equation since you have to add 3 (for the delivery charge) to the numbers.
