Answer 1

at a pizza shop, two small pizzas, a liter of soda, and a salad cost $14;

one small pizza, a liter of soda, and three salads cost $15;

and three small pizzas and a liter of soda cost $16.

Equations:

2p + d + s = 14

p + d +3s = 15

3p + d + 0 = 16

=====================

Use any method you know to solve to get:

p = $5 (price of one pizza)

d = $1 (price of one soda)

s = $3 (price of one salad)

I hope this help you
