Question 1137971
An ice cream parlor offers four flavors of ice cream three sauces, and two
types of nuts. How many different Sundaes consisting of a single flavor of ice
cream plus one or more toppings are possible?
<pre>
Notice that the flavors are not like the toppings.  We can say "yes" to only 1 of the 4 flavors.

So there are only 4 ways to choose the 1 flavor. 

For each of the 4 ways to choose the 1 flavor, we can say "yes" or "no" to each of the 5 toppings.  
So there are 2<sup>5</sup> or 32 ways to choose or reject the 5 toppings.

Answer 4×2<sup>5</sup> = 4×32 = 128 sundaes.
