Question

Ariana orders 4 large pizzas and 1 order of breadsticks The total for her order is $34.46. Emily orders 2 large pizzas and 1 order of breadsticks. $18.48 is the total for her order. Determine the order for 1 large pizza and 1 order of breadsticks?

Answer 1

4p + 1b = 34.46
2p + 1b = 18.48

Solve either equation for b

2p + b = 18.48
b = 18.48 - 2p

Substitute into first equation
4p + 18.48 - 2p = 34.46
2p + 18.48 = 34.46
2p = 15.98
p = $7.99

Plug back into either equation to find cost of breadsticks

2(7.99) + b = 18.48
15.98 + b = 18.48
b = $2.50

One pizza + breadstick
$7.99 + $2.50
$10.49 :)
