Answer:

70\times 6000=420000

Step-by-step explanation:

Given : Expression 'Product of 70 times 6000'.

To find : Calculate the product using associative and commutative properties?

Solution :

Associative property of multiplication,

a\cdot (b\cdot c)=(a\cdot b)\cdot c

Commutative property of multiplication,

a\cdot b=b\cdot a

Now, We solve the expression using properties

70\times 6000=(7\times 10)\times (6\times 1000)

70\times 6000=7\times 10\times 6\times 1000

Applying Commutative property,

70\times 6000=7\times 6\times 10\times 1000

Applying Associative property,

70\times 6000=42\times (10\times 1000)

70\times 6000=42\times 10000

70\times 6000=420000

Whatever happened to just normal 70 times 6,000? The product is 420,000. If that was your question.

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.
