Question

long distance charges to a particular region cost 17¢ per minute. in addition, there is a connection charge of 63¢. which formula best describes the cost c in cents of a long distance phone call lasting m minutes?
○ $c = 63(m + 17)$
○ $c = 17 + 63m$
○ $c = 17m + 63$
○ $c = 63 + m + 17$

Explanation:

Step1: Identify variable cost

Cost per minute: $17M$ cents, where $M$ = minutes

Step2: Identify fixed cost

Connection charge: $63$ cents

Step3: Total cost formula

Add variable + fixed cost: $C = 17M + 63$

Answer:

C. $C = 17M + 63$
