Using a rain gauge, Gerry determined that 1/2 inch of rain fell during 3/4 of an hour.What is the unit rate of rainfall in inches per hour
Goals per game. This is calculated per game so the rate will be number of goals divided by the games played hence “Goals Per Game”
Answer:
the second choice 25x+75.50<525
Let x be the number of passengers.
The discounted cost is given by,
Cost = 574-5(x-81) = 574-5x + 405 = 979 -5x
Total revenue, R(x) = x(979 - 5x) = 979x - 5x^2
At maximum revenue, dR/dx = 0 => dR/dx = 979 - 10x = 0 =>10x = 979 => x =979/10 = 97.9 ≈ 98 passengers
Therefore,
Revenues, R(97) = 98[574 -5(98-81)] = 98[574-85] = $47,922
