Final answer:
The receptionist will answer approximately 8505 calls per week.
Step-by-step explanation:
To find the number of calls the receptionist will answer, we need to multiply the number of calls received per hour by the number of hours worked per week.
Given that the company receives about 189 calls per hour and the receptionist works a 45-hour week, the number of calls she will answer can be calculated as:
Total calls answered = Calls per hour * Hours worked per week
Total calls answered = 189 calls/hour * 45 hours/week = 8505 calls/week
Therefore, the receptionist will answer approximately 8505 calls per week.
