Marcy is a makeup artist and has agreed to do some makeup for her friend's wedding. The only makeup she has limited stock of is lip gloss so she counts how many tubes she needs. Each tube of lip gloss will hold enough lip gloss for 3 people's makeup. Marcy decides to bring 6 tubs of lip gloss, each of which holds 2 tubes of lip gloss, and this will be the exact amount she needs for everyone's makeup. How many people is Marcy painting with makeup? Think carefully first, then make a decision:
Marcy is bringing 6 tubs of lip gloss * 2 tubes of lip gloss per tub of lip gloss = 12 tubes of lip gloss. So she must be applying makeup to 12 tubes of lip gloss * 3 people per tube of lip gloss = 36 people. So, the answer is 36.
