Answer:

r'(t) = 298t  -850

Step-by-step explanation:

Given

q(t) = 1000t - 150t^2

p(t) = 150t - t^2

Required

r'(t)

First, we calculate the revenue

r(t) = p(t) - q(t)

So, we have:

r(t) = 150t - t^2 - (1000t - 150t^2)

Open bracket

r(t) = 150t - t^2 - 1000t + 150t^2

Collect like terms

r(t) = 150t^2 - t^2 + 150t - 1000t

r(t) = 149t^2  -850t

Differentiate to get the revenue change with time

r'(t) = 2 * 149t  -850

r'(t) = 298t  -850

At Greenwood Landscaping, rock costs $47.50 per ton. How much would 2.5 tons cost?
Grace [21]

Answer:

Hey!

Your answer is $118.75!

Step-by-step explanation: How did I get this?

<u>STEP 1:</u> So we know that for a ton of rock costs us $47.50...

To get 2 tons all we have to do is to MULTIPLY $47.50 by 2...

<em><u>(47.50 x 2 = 95)</u></em>

<u>STEP 2: </u>So for $95, you will get 2 tons of rock!

Now to get the .5 tons of rock in price form, we have to get the price of the whole 2.5 tons and DIVIDE BY 2

<em><u>(47.50 ÷ 2 = 23.75)</u></em>

<u>STEP 3:</u> So now we have the costs for 2 tons and the price for HALF a ton.

What we do now is easy...we ADD THE VALUES TOGTHER!

<em><u>(95 + 23.75 = $118.75)</u></em>

The result of $118.75 after adding them together is the PRICE OF 2 TONS!

<u>I HOPE THIS HELPED YOU!</u>
