Answer:
The two values of production level are:
x = 20
or
x = 140
Step-by-step explanation:
Let's write the Profit equation by subtracting the cost function from the revenue one:
Now, we set to find the production level "x" to give us a profit of $ 700:
So we solve this quadratic equation using the quadratic formula:
which gives two posible solutions: x = 20, or x = 140
Answer:
Negative

Answer:
7a^2-ab-9b^2
Step-by-step explanation:
Let's do this in two steps. First, we multiply the first two parentheses:
(a+2b)(4a-5b)
4a^2-5ab+8ab-10b^2 = 4a^2+3ab-10b^2
Then, do the other two parentheses:
(3a-b)(b-a)
3ab-3a^2-b^2+ab = 4ab-3a^2-b^2
Then, combine them:
4a^2+3ab-10b^2-4ab+3a^2+b^2 = 7a^2-ab-9b^2
---------------------
given:
= cost of Brazilian coffee in mixture
= cost of Venezuelan coffee in mixture
= cost of mixture
---------------------
Now I can rite these equations:
(1)
(2)
Multiply both sides of (2) by and
subtract from (1)
(1)
(2)
and, since
288 kg of Brazilian coffee and 96 kg of Venezuelan coffee are needed
