Jess recently started a business producing cosmetic products made from natural ingredients. she wants to advertise her products by distributing bags of samples in her neighborhood. she calculated that it takes a person 2 minutes to prepare one bag. how many hours will it take to prepare 1200 bags of samples if jess and 7 of her friends work simultaneously?

Okay so there are 8 people total working on the bags and it takes 2 minutes per bag. That means in two minutes, 8 bags get done. Or in other words, to make it simplier, 4 bags in one minute. 1200/4 = 300. It will take 300 minutes with all of jess and her friends working together to make 1200 bags. 300/60 is 5. It will take 5 hours (converting minutes to hours) for Jess and her friends to finish 1200 bags, each person taking 2 minutes per bag.

You have got to take a better picture. i can't you if i can't see what i'm trying to you with.. okay.

Logical equivalent of the give question is its contrapositive
