Respuesta :

Answer:

Hence there 329 different possible meals that the restaurant offer.

Step-by-step explanation:

Given:

A restaurant offers 5 choices of appetizer,10 of meal and 4 of dessert.

To Find:

All different possible ways that restaurant offers the meal.

Solution:

Consider ,

A=appetizer Course=5

M=main  course=10

D= Desert course=4.

For ,

All individual course=total courses=A+M+D

=5+10+4

=19

So there 19 ways to eat just one course from restaurant.

Now,

For 2 different choices

It is given by combination of 2 courses with each other

=AD+AM+DM

=5*4+5*10+10*4

=20+50+40

=110

So there 110 ways to eat 2 different courses.

Now

For 3 different choices

It is given by

=A*D*M

=5*10*4

=200

So there 200 ways to eat 3 different courses.

Now,

All choices available = (ways to eat one course only +ways to eat 2 different courses+ways to eat 3 different courses)

=19+110+200

=329
