g A restaurant offers 7 entrees and 11 desserts. In how many ways can a person order a two-course meal?

Kitty [74]

Answer:

$2-course\ meal = 77\ ways$

Step-by-step explanation:

Given

$Entrees = 7$

$Desserts = 11$

Required

Determine the number of ways to get a two-course meal

This is solved as follows:

<em>The entrees can be ordered in 7 ways</em>

<em>The desserts can be ordered in 11 ways;</em>

$2-course\ meal = Entrees * Desserts$

Hence:

$2-course\ meal = 7 * 11$

$2-course\ meal = 77\ ways$
