Natalie paid $20.7 for 3 small pizzas and a salad which was $3.

a- Write an equation to represent the situation

b- solve the equation to find the cost of one pizza. Show your work

Answer 1

Part A
$20.70=3p+3
Part B
$20.70=3p+3
$17.90=3p
$5.90=p
So the cost of one pizza is $5.90

Answer 2

Explanation:

a) Let the cost of a Pizza = $ x

Cost of three pizza's = 3 *x = 3x

cost of 3 pizza + cost of a salad = $ 20.7

3x + 3 = 20.7

b) 3x + 3 = 20. 7 {Subtract 3 from both sides}

3x = 20.7 - 3

3x = 17.7 {Divide both sides by 3}

x = 17.7/3

x = 5.9

Cost of one pizza = $ 5.9
