1 answer:
Answer:
The hot dog are $2.63
Step-by-step explanation:
Hot Dogs = H
Drinks = D
2H + 2D = 4
Divide both sides by 2
H + D = 2
Subtract D from either side
H = 2 -D
3H + D = 4.50
Plug in 2 - D for H
3(2- D ) + D = 4.50
6 - 3D + D = 4.50
6 - 4D = 4.50
Add 6 to either side
-4D = 10.50
Divide either side by -4
D = -2 . 625

This answer is not 3/4. The answer is 1/10. I found this by knowing that there are 10 numbers and there is a 1/10 chance that it will start with 7. I would really appreciate it if I could get brainliest. Thanks!! =D
