Question

select the correct answer. chris has a cell phone plan with a flat fee of $26.00 per month, plus a cost of $0.12 per minute of usage. chris can only afford a monthly bill of $86.00. which statement is true? a. chris needs to use fewer than 400 minutes per month. b. chris needs to use fewer than 450 minutes per month. c. chris can afford to use up to 500 minutes per month. d. chris can afford to use up to 550 minutes per month.

Explanation:

Step1: Subtract flat - fee from total budget

Let $m$ be the number of minutes. The total cost equation is $C = 26+0.12m$, where $C$ is the total cost. We know $C = 86$. First, subtract the flat - fee from the total budget: $86 - 26=60$.

Step2: Calculate number of minutes

Since the cost per minute is $0.12$, and we have $60$ dollars left for minutes, we find the number of minutes by dividing the remaining money by the cost per minute. So, $m=\frac{60}{0.12}=500$.

Answer:

C. Chris can afford to use up to 500 minutes per month.
