Answer:
Answer: 350
Step-by-step explanation:
Explanation:
a = adult tickets
s = student tickets
║ a + s = 754
║s = a + 54
Plug s = a + 54 into a + s = 754
a + (a + 54) = 754
a + a + 54 = 754
2a + 54 = 754
2a = 754 - 54
2a = 700
a = 350
1 divided by 18 is .111111111
Answer:
N(x) = 40 - 2x
P(x) = -2x² + 52 x - 240
maximum profit = 13
Step-by-step explanation:
given data
feeder cost = $6
average sell = 20 per week
price = $10 each
solution
we consider here price per feeder = x
and profit per feeder id here formula = x - 6
so that here
total profit will be
P (x) = ( x - 6 ) Nx
here N(x) is number of feeders sold at price = x
so formula for N (x) is here
N(x) = 20 - 2 ( x - 10 )
N(x) = 40 - 2x
so that
P(x) = (x-6) ( 40 - 2x)
P(x) = -2x² + 52 x - 240
since here
a = -2
b = 52
c = -240
a < 0
so quadratic function have maximum value of c -
so it will be
maximum value = -240 -
maximum value = 98
so here maximum profit attained at
x =
x =
x = 13
maximum profit = 13
The answer in simplest for would be 7/8. What you basically do is multiply 7/10 by the reciprocal of 4/5 and that gives u the answer.
