Alexandra has a stand in the marketplace where she sells her cumin for 7.20 per kilogram. If she sells 90 kilograms of cumin her
Drupady [299]

Answer:

$234

Step-by-step explanation:

First we need to define profits. Profits are Income minus Expenses:

P = I - E

We know profits are $414, so:

414 = I - E

We also can calculate income, as it is equal to price by the sales:

I = p*Q

Here she sold 90 kgs at $7.20 b kg. So:

I = p*Q = 7.20 * 90 = 648

So, replacing in profits equation:

414 = I - E

414 = 648 - E

If we sum E in both sides:

414 + E = 648 - E + E = 648

414 + E = 648

Now, subtracting 414 in both sides:

414 + E - 414 = 648 - 414

E = 234

So, her expenses are $234

(URGENT!!!) Can someone help me with this? For part a), would the equation A=200(15)^m=395 work? In part b), can't I just factor
Levart [38]
A.) 200+15m=395. This is because the initial price is 200, and after that she will add $15/month. The equation you chose would be exponential, meaning the rate would increase as time passed, which is not the case. Instead, the rate is constant, and the only think that changes is m, the number of months.

b.) I believe it will be easier to answer with ^this equation.

c.) The rate of change would be 15, since the rate is increasing monthly by $15.

d.) Once you solve 209+15m=495, you'll have the answer.

Answer:

Is only if a Biconditional?

The general form (for goats, geometry or lunch) is: Hypothesis if and only if conclusion. Because the statement is biconditional (conditional in both directions), we can also write it this way, which is the converse statement: Conclusion if and only if hypothesis.
