Question

a culinary club earns $1360 from a dinner service. they sold 45 adult meals and 80 student meals. an adult meal costs twice as much as a student meal. what is the cost of an adult meal?

Answer 1

The adult meals cost 16$ and the student meals cost 8$. A=16 and S=8. 80•8= 640 you then take eight and multiply it by two and get 16 because it says the adult meals were twice as much. 45•16= 720.
640+720= 1360
