Yuri [45]

$7.95 x h = $236.50
$7.95 x 18 = $143.10

$236.50 - $143.10 = $93.4
7.95 x h = $93.4
$93.4 / $7.95 = 11.7 hours

h = 12 hours

one particular ice cream parlor has 28 different flavors available. How many ice cream cups are possible if you order 4 scoops?

Lena [83]

Answer:

20,475 cream cups are possible.

Step-by-step explanation:

The order in which the flavors are chosen is not important, which means that the combinations formula is used to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question:

4 cups from a set of 28.

$C_{28,4} = \frac{28!}{4!24!} = 20475$

20,475 cream cups are possible.
