A group was selling hot dogs and soda before a game. Hot dogs cost $1.50 and sodas cost $0.75. At the end of an hour, they sold 15 items and collected $18. How many hot dogs and sodas did they sell?

Answer 1

they sold 9 hot dogs and 6 sodas

H+S = 15

1.5H + .75S = 18

1.5H + 1.5S = 22.5

1.5H + .75S=18 subtract to get

.75S = 4.5

S = 4.5/.75 = 6 sodas

H = 15-6 + 9 hot dogs
