he Springfield Friends Foundation collects donations of money. They spend every dollar they receive on programs for different co

mmunity charities. Donations are recorded as positive values. The costs of programs are recorded as negative values. For the last month, the records show that the Foundation received donations of $250, $1,000, $500, and a fourth donation that was incorrectly recorded. The foundation used all four donations to fund a program. The cost of the program was listed as −$2,000, and they had nothing left over. What was the value of the fourth donation?

Answer: The fourth donation was $250

Step-by-step explanation: Note that doantions are recorded as positive values and the costs are recorded as negative values. They received four donations and used up all money collected without any leftover.

The donations received were as follows;

250 + 1000 + 500 + x

The total amount spent was 2000 (recorded as a negative value)

Therefore the fourth donation which is x can be calculated as follows;

250 + 1000 + 500 + x = 2000

1750 + x = 2000

Subtract 1750 from both sides of the equation

x = 250

The value of the fourth donation is $250

Since profit can't be negative, the production level that'll maximize profit is approximately equal to 220.

<h3>How to find the production level that'll maximize profit?</h3>

The cost function, C(x) is given by 12000 + 400x − 2.6x² + 0.004x³ while the demand function, P(x) is given by 1600 − 8x.

Next, we would differentiate the cost function, C(x) to derive the marginal cost:

C(x) = 12000 + 400x − 2.6x² + 0.004x³

C'(x) = 400 − 5.2x + 0.012x².

Also, revenue, R(x) = x × P(x)

Revenue, R(x) = x(1600 − 8x)

Revenue, R(x) = 1600x − 8x²

Next, we would differentiate the revenue function to derive the marginal revenue:

R'(x) = 1600 - 8x

At maximum profit, the marginal revenue is equal to the marginal cost:

1600 - 8x = 400 − 5.2x + 0.012x

1600 - 8x - 400 + 5.2x - 0.012x² = 0

1200 - 2.8x - 0.012x² = 0

0.012x² + 2.8x - 1200 = 0

Solving by using the quadratic equation, we have:

x = 220.40 or x = -453.73.

Since profit can't be negative, the production level that'll maximize profit is approximately equal to 220.
