<h3>
Answer:</h3>
50 people
<h3>
Step-by-step explanation:</h3>
Let x represent the number of people on the cruise. The amount they each must pay is ...
... ($58 -(x -42)) = $100 -x
The revenue from the group is the product of the number of people and the amount each pays:
... r(x) = x·(100 -x)
This describes a downward-opeing parabola with zeros at x=0 and x=100. The vertex (maximum) will be found halfway between those zeros, at x=50.
A group size of 50 maximizes revenue from the cruise.
Not to be mean Fernanda but it wouldn't be 0 it actually would be 0.19444444 so I would just put 0.194 and put a line over the 4 to show that it repeats continuously
Answer:
The answer to your question is: no
Step-by-step explanation:
Data
Fastest time = 27.93 s
Second fastest time = 27.97 s
Claire's time = 27.99 s
Just remember that to win a race, the athete that wins must register the lowest time.
Substract Claire's time from the fastest time, if the result is positive, Claire ran slower, if the result is negative Claire ran faster than the previous Girls.
Difference 1 = 27.99 - 27.93 = 0.06 positive, Claire ran slower
Difference 2 = 27.99 - 27.97 = 0.02 positive, Claire ran slower.
