the maximum amount of rides is 20.

REASONING: you take away $20 from $80 so you can ride home on the Uber, and get in. then divide the remaining 60 by 3, leaving you with 20.

Answer:

Step-by-step explanation:

F=Fair cost, r=ride, U=uber cost. I=initial money

F=10+3r

The money you currently have($80) minus the $10 uber fee should be greater than 0 after the rides you went to. Here's the equation:

I-U>=10+3r

80-10>=10+3r

70>=10+3r=>Complex inequality

60>=3r

r<=20=>20 rides

Alisiya [41]

Answer:

The singers can finish first through fifth in 360360 ways.

Step-by-step explanation:

The order of the singers is important, because they are ranked by positions. So we use the permutations formula to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

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

In this question:

Top five singers, from 15 finalists. So

$P_{(15,5)} = \frac{15!}{(15-5)!} = 360360$

The singers can finish first through fifth in 360360 ways.
