Yesterday, a movie theater sold 301 bags of popcorn. A large bag of popcorn costs $3. A small bag of popcorn costs $1. In all, the movie theater made $507 from popcorn sales. Write and solve a system of equations to find how many bags of each size of popcorn were sold.
Oh thats easy!!! s-small popcorn $1 L- large popcorn $3 Total money-$507 Total bags-301 Equation: 3L+1S=$507 L+S=301 subtract by substituting
2L=206 divide L (or y)=103
3(103)+1S=507 replace"L" for 103, then multiply 309+1S=507 subtract 309 from 507 1S=198-----> S(or x)=198 Coordinates are (198,103) Hope this helps... Enjoy and Merry Early Christmas!!!!
