Answer:

Ashley and her 4 friends would required 5.33 hours to repair 1575 bags of sample.

Explanation:

75% is written as 0.75 as a decimal or 3/4 as a fraction.

Her friends take 75% longer, so multiply the time it takes Ashley by 1 + the percentage: 1.75 as a decimal or
1 (3)/(4) \ \ or \ \ (7)/(4) as a fraction.


(2)/(3) * (7)/(4) =(14)/(12) = 1 (2)/(12) = 1 (1)/(6) minutes.

1 hour = 60 minutes.

Divide minutes in an hour by minutes per pack:

Ashley can pack:
(60)/((2)/(3)) = 90 \ bags\ per \ hour

1 friend can pack:
(60)/(1(1)/(6))=(360)/(7) = 51 (3)/(7) \ bags \ per \ hour.

multiply the amount 1 friend can pack by 4 friends:
51 (3)/(7) * 4 = \frac {1440}{7} = 205 (5)/(7) \ bags \ per \ hour

Ashley and her friends can pack
90 + 205 (5)/(7) = 295 * (5)/(7) \ bags \ per \ hour.

Now divide the total bags by bags per hour:


(1575)/(295 (5)/(7)) = 5.33 \ hours ( Round answer as needed.)

Hence, Ashley and her 4 friends would required 5.33 hours to repair 1575 bags of sample.
