Step-by-step explanation:
Answer:
- Burgers - $8.29 and fries - $4.39
Step-by-step explanation:
<u>Let burgers - b, fries - f</u>
- 8b + 3f = 79.49
- 12b + 6f = 125.82
<u>Double the first equation and subtract the second equation:</u>
- 16b + 6f - 12b - 6f = 2(79.49) - 125.82
- 4b = 33.16
- b = 33.16/4
- b = 8.29
<u>Find f:</u>
- 8(8.29) + 3f = 79.49
- 3f = 79.49 - 66.32
- 3f = 13.17
- f = 13.17/3
- f = 4.39
2x + y = 3 is the blue boundary line...the shading is below the line which means 2x + y is less than or equal to 3
y - x = 2 is the red boundary line... the shading is above the line which means
y - x is greater than or equal to 2
ANSWER: 2x + y is less than or equal to 3 and y - x is greater than or equal to 2
