tankabanditka [31]
First we need to calculate the total cost.

The seniors will rent limousine from 8:00 pm till 1:00 am. So total time of rent = 5 hours

Total charges = Charges of first 3 hours + Charges of next 2 hours + Tip
So,
Total charges = $180 + 2($30) +$20 = $260

Thus the total amount the 8 seniors will have to pay is $260. The amount each senior will have to pay is $260/8 = $32.5

Therefore, each student will have to pay $32.5

Tina must select and answer in any order three of seven
Leno4ka [110]

Answer:

Tina can select and answer the essay questions on her test in 35 ways.

Step-by-step explanation:

The order in which she chooses the questions is not important. For example, choosing questions 1, 3 and 7 is the same as choosing 7, 3 and 1. So we use the combinations formula 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:

Three questions from a set of 7. So

C_{7,3} = \frac{7!}{3!(7-4)!} = 35

Tina can select and answer the essay questions on her test in 35 ways.
