Mrs. welch and her 6 children are shopping at a local grocery store. each of the children will be allowed to select one box of cereal for their own from the 8 different boxes of cereal available (there are no two the same). in how many ways can the selections be made?

20160

Step-by-step explanation:

Given: The number of different boxes of cereal available = 8

The number of children are shopping at a local grocery store =6

Since, each of the children will be allowed to select one box of cereal for their own from the 8 different boxes of cereal available and there are no two the same.

Then by using permutation, the number of ways the selections can be made is given by :-

Hence, the  number of ways the selections can be made = 20160

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
