You are buying snacks for your friends at the movies. You are given $ 17 to spend and chocolate bars cost $ 2 while bags of popcorn cost $ 3. You need to buy 7 snacks (one for each of your 6 friends plus 1 for you). How many chocolate bars should you buy? How many bags of popcorn should you buy? (Define your variables and solve for them)

4 chocalate, and 3 bags

Step-by-step explanation:

2x+3y=17

x+y=7

x=7-y

2(7-y)+3y=17

14-2y+3y=17

14+y=17

y=3

x+3=7

x=4

You should buy 4 chocalate bars, and 3 bags of popcorn.

 7 chocolate bars and 1 bag of popcorn
