Answer:
The length is 95 m
Step-by-step explanation:
P = 2(l+w) where l is the length and w is the width
342 = 2(l+76)
Divide each side by 2
342/2 = 2/2(l+76)
171= l+76
Subtract 76 from each side
171- 76 = l+76-76
95 = l
Answer:
20 passengers at $960 each
Step-by-step explanation:
Assuming at least 20 people sign up for the cruise, determine how many passengers will result in the maximum revenue for the owner of the yacht.
(a) Find a function R giving the revenue per day realized from the charter.
R(x) =
(b) What is the revenue per day if 48 people sign up for the cruise?
$
(c) What is the revenue per day if 78 people sign up for the cruise?
$
revenue (R) = (20+x)(960-8x)
= 19200 - 160x + 960x -8 x^2
dR/dx = -160 + 960 - 16x = 0 for a max of R
16x = 800
x = 50
