Question:

Local pizza joint sold a total of 1600 small pizzas at $9 and pasta dinners at $13 during the Super Bowl how many of each did they sell if total sales were $15,600? ​

Answers

s=small pizzas

p=pasta dinners

s+p=1600

9s+13p=15600

multiply first equation by -9 and add to the second one

-9s-9p=-14400

9s+13p=15600 +

0s+4p=1200

4p=1200

divide by 4

p=300

go back

s+p=1600

s+300=1600

minus 300 both sides

s=1300

1300 small pizzas

300 pasta dinners
