Solve the problem.A wireless service charges $36.50 for 800 minutes in the primary calling zone, the $0.10 for each additional minute in the calling zone. Calls placed outside of the calling zone cost $0.14 per minute. Suppose a subscriber uses 1078 minute in the calling zone and 38 minutes outside the calling zone. Write a numerical expression that describes the total cost for the month, then calculate the total.
A. 36.5 + 0.10(38) + 0.14(1078 - 800) = $79.22
B. 36.5 + 0.10(1078 - 800) + 0.14(38) = $69.62
C. 36.5 + 0.14(1078 - 800) + 0.14(38) = $45.62
D. 36.5 + 0.10(1078) + 0.14(38) = $149.62
