Question 1045004: Set up an equation and solve. Write a sentence explaining your answer.
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. How many calls can be made per day?
My wrong answer:
14,000/123=117
It will be easiest to solve this problem if you convert everything to seconds first. 4 hours is 14,400 seconds and 2 minutes and 3 seconds is 123 seconds. Then all you have to do is divide 14,400 by 123 for the total number of calls that can be made per day.
Need it in the form of an equation.

This part describes arithmetic Addition.
It takes 3 seconds to dial the number and each call takes 2 minutes.

The question is to find number of calls. The quoted part above is for "per call".

Identify and use the ratios given.

-

You will need to decide what time units you want and convert using an appropriate conversion ratio.

I suggest to convert the mixed unit ratio into MINUTES per CALL ; and convert the "4 to 1" ratio into MINUTES per DAY.

.
The equation is

123*n = 14400.

Solve for n: n = = 117.07 . . .

and take the maximal integer <= as the final answer: 117.
