Total number of tickets = 1840
a) x = $20 tickets.
y = $30 tickets.
so answer of part a) is x + y = 1840
b) 20*x = total money received by selling $20 tickets.
therefore answer of this part is 20*x
c) Similarly the answer of this part is 30*y
d) Total sale = 42800
20*x + 30*y = 42800 ( this is the answer of part d)
e) We get two equations as
x + y = 1840 ....( 1 ) and 20x + 30y = 42800 ....( 2 )
from equation ( 1 ), we get y = 1840 - x
Plug this value in equation ( 2 ), we get:
20x + 30(1840 - x ) = 42800
20x - 30x = 42800 - 55200 = -12400
-10x = -12400
x = 1240
plug this value in equation ( 1 ), we get:
1240 + y = 1840
y = 1840 - 1240 = 600
Therefore, x = 1240 and y = 600

1)A linear cost function is C(x) = 6x + 450. (Assume C is measured in dollars.) (a) What are the slope and the C-intercept? slope C-intercept (b) What is the marginal cost MC ? MC= What does the marginal cost mean? Each additional unit produced costs this much (in dollars). If production is increased by this many units, the cost decreases by $1. Each additional unit produced reduces the cost by this much (in dollars). If production is increased...
A concert promoter sells tickets and has a marginal-profit function given below, where P'(x) is in dollars per ticket. This means that the rate of change of total profit with respect to the number of tickets sold, x, is P'(x). Find the total profit from the sale of the first 200 tickets, disregarding any fixed costs. P'(x) = 3x - 1140 The total profit is $ (Round to the nearest cent as needed.)
