Question

wiley purchased a 30 - day international cell phone plan for use during winter break. there is a one - time fee of $35 and it includes 150 mb of data usage. each extra megabyte, or part thereof, of data costs $0.28. find the cost of the plan if he uses 388 mb of data during the trip.

Explanation:

Step1: Calculate extra data usage

The plan includes 150 MB of data. The user used 388 MB. So the extra data usage is $388 - 150=238$ MB.

Step2: Calculate cost of extra data

Each extra megabyte costs $0.28$. So the cost of extra data is $238\times0.28 = 66.64$.

Step3: Calculate total cost

There is a one - time fee of $35$. The total cost is the sum of the one - time fee and the cost of extra data, which is $35+66.64 = 101.64$.

Answer:

$101.64$
