The telemarketer can make 117 calls per day
<em><u>Solution:</u></em>
Given that a telemarketer has 4 hours a day to call people for a survey
It takes 3 seconds to dial the number and each call takes 2 minutes
<u><em>To find: Number of calls made in 1 day</em></u>
From given statement,
Total number of hours = 4 hours
<em><u>Convert 4 hours to minutes</u></em>
1 hour = 60 minutes
4 hours = 4 x 60 = 240 minutes
Time taken to dial the number = 3 seconds
<em><u>Convert 3 seconds to minutes</u></em>
Use the following conversion factor
Thus,
Time taken to dial the number = 0.05 minute
Time taken for call = 2 minutes
Total number of time = 240 minutes
Let "x" be the number of calls made per day
Total number of time = x(Time taken to dial the number + Time taken for call)
Therefore, we get
240 minutes = x(0.05 minute + 2 minute)
240 = x(2.05)
2.05x = 240
x = 117
Thus 117 calls can be per day
