Answer: you can use 260 min, 60 min at a fixed price ($20) and extra 200.
Step-by-step explanation:
C(x) = 20 + 0.20(x − 60)
C(x) ≤ 60
20 + 0.20(x − 60) ≤ 60
0.20(x − 60) ≤ 60 - 20
0.20x - 12 ≤ 40
0.20x ≤ 40 + 12
0.20x ≤ 52
x ≤ 52/0.2
x ≤ 260
This way, you can use 260 min, 60 min at a fixed price ($20) and extra 200.
I’m not sure if you’re looking for the solution but if you are the equation is
Y= -2x -5
Answer:
26.8336 ≈ 26.83
Step-by-step explanation:
If x < 5, then we round down.
If x ≥ 5, then we round up.
2 decimal places is the hundredths place.
26.83<u>3</u>6
3 < 5, so we round down
26.83
