Step-by-step explanation:
2 < x < 4 and 3 < y < 7
We have (2 + 3) < (x + y) < (4 + 7),
Therefore 5 < x + y < 11.
The largest integer value for
x + y is 10.
Answer:
a) C(1,000)=288,491.11 $
b) c(1,000)=288.49 $/u
c) dC/dx(1,000)=349.74 $/u
d) x=100 u
e) c=220 $/u
Step-by-step explanation:

(c) Find the marginal cost at a production level of 1000 units.

(d) Find the production level that will minimize the average cost.

(e) What is the minimum average cost?

Answer:
D
Step-by-step explanation:
Let x be Bill’s scores.
Let y be Theo’s scores.
x + y = 90
x² = y
Solve for x in the second equation.
x = √y
Put x as √y in the first equation and solve for y.
√y + y = 90
√y = 90 - y
y = (90 - y)²
y = - y² - 180y - 8100
0 = -y² - 181y - 8100
0 = (-y+81)(y-100)
-y+81=0
y = 81
y - 100 = 0
y = 100
100 does not work if we plug in to check, so y is 81.
y = 81
Put y as 81 in the first equation and solve for x.
x + 81 = 90
x = 9
Bill scored 9 goals and Theo scored 81.

Answer:
202.90
Step-by-step explanation:
If 187.90 is the price before the sales tax, you will multiply it by the 0.08 tax which will give you 15.032. You take 15.032 and add it to 187.90 because that is the sales tax. And after you add it and round to the nearest cent you get 202.90
