Answer:
2 packs
Step-by-step explanation:
Since there is 10 packs just divided it by how many notebooks were in the pack.
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.
