Acatering service offers 9 appetizers, 3 main courses, and 10 desserts. a banquet chairperson is to select 7 appetizers, 2 main courses, and 7 desserts for a banquet. in how many ways can this be done?

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to
