A total of seventeen thousand nine hundred passengers ride a certain subway line during the morning rush hour. The ticket prices for a ride are $108 for junior and high school students, $2. 18 for adults, and $1.08 for senior citizens, and the revenue from those riders is $36,932. If the ticket prices were raised to $1.24 for junior
and high school students and S2.50 for adults, and the senior citizen
price were unchanged the expected revenue from these riders would be 542,228. How many
riders in each category normally ride the subway during the morning rush hour?
During the morning rush hour, junior and high school students, adults, and seniors ride the train,
.

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
