Ben ordered 20 total items consisting of pizza and sodas.  A pizza is $10, a soda is $2, and he spent a total of $72.  Which system models this scenario?

10P + 2S = 20
P + S = 72

P + S = 20
2P + 10S = 72

P + S = 20
10P + 2S = 72

y = 10x + 2

y = 72x + 20

Mr. Riley bought 8 tickets to a chili supper and spent a total of $30. He bought a combination of adult tickets for $5 each and child tickets $3 each. Which system of equations below will determine the number of child tickets, c, and the number of adult tickets, a, he bought?

y = 8x + 30

y = 5x + 3

a + c = 8

3a + 5c = 30

5a + 3c = 8

a + c = 30

5a + 3c = 30

a + c = 8

A large pizza at Palanzio’s Pizzeria costs $6.80 plus $0.90 for each topping. The cost of a large cheese pizza at Guido’s Pizza is $7.30 plus $0.65 for each topping. Which system of equations could be used to find the number of toppings when both companies cost the same amount? 

y = 6.80 + .65x
y=7.30+.90x

x + y = 6.80
x + y = 7.30

y = .90x + 6.80
y = .65x + 7.30

y + .90x = 6.80
y + .65x = 7.30
