Phantasy [73]

Answer:

The amount in checking will always be twice in any week.

Step-by-step explanation:

Let's say, w represents the week, s represents the saving account and c represents the checking account.

Balance in saving account in any week =s=5w+25

Balance in checking account in any week  =c=10w+50

Translate the statement into mathematical equation. Remember to use " = " for word "is" in the given statement.

We have to find w for 2s = c.

Putting the values, we have:

2(5w+25)=10w+50

\Rightarrow \mathrm{True\:for\:all}\:w

Which means in each week the amount in checking is twice the amount in savings.

Best Regards!

The profits of a company are found by subtracting the company's costs from its revenue. If a company's cost can be modeled by 14
evablogger [386]

Answer:

-0.0002x^2 +26x-120000

Step-by-step explanation:

The correct question should be:

We have been told that all we have to do to get profit is to subtract the cost from revenue.

Revenue = 40x - 0.0002x^2

Cost <em>= </em>14x + 120,000<em />

<em />

Hence:

Profit = 40x - 0.0002x^2 - (14x + 120000)

40x - 0.0002x^2 - 14x - 120000\\\\40x - 14x - 0.0002x^2 - 120000\\\\26x - 0.0002x^2 - 120000

Putting it in ordered form:

-0.0002x^2 +26x-120000

This is an expression for the profit.
