Answer:
Step-by-step explanation:
<u>The equation to reflect the monthly plans:</u>
- Plan A f(x) = 0.16x + 12
- Plan B g(x) = 0.12x + 29
<u>We need to find the value of x when f(x) = g(x):</u>
- 0.16x + 12 = 0.12x + 29
- 0.16x - 0.12x = 29 - 12
- 0.04x = 17
- x = 17/0.04
- x = 425 minutes
<u>The cost is:</u>
