Ashley recently opened a store that uses only natural ingredients. she wants to advertise her products by distributing bags of samples in her neighborhood. it takes ashley 2/3 of a minute to prepare one bag. it takes each of her friends 75% percent longer to prepare a bag. how many hours will it take ashley and 4 of her friends to prepare 1575 bags of samples?
plz

answer: 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 (7/4) as a fraction.

2/3 x 7/4 =14/12 = 1 2/12 = 1 1/6 minutes.

1 hour = 60 minutes.

divide minutes in an hour by inutes per pack:

ashley can pack: 60 / 2/3 = 90 bags per hour

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

multiply the amount 1 friend can pack by 4 friends: 51 3/7 x 4 = 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.)
