Question

write a system of equations for the following problem and then solve the system using the method of your choice. At a concession stand for a basketball game, students sell soda for 1.25 each, and popcorn for 1.50 each. if the revenue for selling 163 items was $215 how many items were sold

Answer 1

1.25s+1.50p=215
s+p=163

2(1.25s+1.50p)=2(215)
-3(s+p)=-3(163)

2.5s+3p=430
-3s-3p=-489

-.5s=-59

s=118
t=45

1.25x118=147.5
215-147.5=67.5
67.5/1.5=45
