Final answer:
The cost for making a 5-minute call, with a rate of 45 cents per minute, is 225 cents.
Step-by-step explanation:
The cost for making a 5-minute call with an international calling plan that charges 45 cents per minute can be calculated by multiplying the number of minutes by the rate per minute. Since every fraction of a minute is charged as a full minute, the entire duration of the call is counted in whole minutes. Therefore, for a 5-minute call:
Cost = 5 minutes × 45 cents per minute
Cost = 225 cents
