Question

you are at a baseball game and bought food for you and your friends. hot dogs cost $1.50 each and chips are $0.75. you spent $20.25 total and got a total of 19 items. How many hot dogs did you buy?

Answer 1

Explanation:

x + y = 19

1.5x + .75y = 20.25

x + y = 19

150x + 75y = 2025

-150x - 150y = -2850

150x + 75y = 2025

-75y = -825

y = 11 bags of chips

x + 11 = 19

x = 8 hot dogs
