I’m pretty sure the correct answer is B
Both computers will do the job in 5 hours and 14 minutes.
Since a computer can process the payroll for Hometel in 10 hours, while an older back up computer needs 11 hours to process payroll, to determine how long would the job take if the two computers are both used to do the job, the following calculation should be performed:
- X / 10 + X / 11 = 1
- 10X + 11X = 110
- 21X = 110
- X = 110/21
- X = 5.238
- 100 = 60
- 0.238 = X
- 0.238 x 60/100 = X
- 0.14 = X
Therefore, both computers will do the job in 5 hours and 14 minutes.

The given temperatures of 70 °F, 50 °F, and 35 °F, at the given 3, 3, and
6 days give the following step function;
- Please find attached the graph of the step function?
<h3>How can the step function be written?</h3>
The temperature at it is fermented in the first three days = 70 °F
From day 3 to 6 the temperature = 50 °F
From day 6 to day 12, the temperature at which it is kept in the freezer = 35 °F
The step function is therefore;
The graph of the above function created with MS Excel is attached
