Given:
Day Hamburger Hot dog Sales
1 200 150 1,450
2 200 250 1,750
Let y be the price of the hamburger and x be the price of the hot dog.
200y + 150x = 1,450
-(200y + 250x = 1,750)
- 100x = -300
x = -300/-100
x = 3
Each hot dog costs $3.
Day 1:
200y + 150(3) = 1,450
200y = 1,450 - 450
200y = 1,000
y = 1,000/200
y = 5
Day 2
200y + 250x = 1,750
200(5) + 250(3) = 1,750
1000 + 750 = 1,750
1,750 = 1,750
The cost of a Hamburger is $5 while the cost of a Hot dog is $3.
