For each question, answer these

a) How much is deposited at the end of each time period   M   or  PMT

b) What is the yearly interest rate expressed as a decimal?

c) How many times a year does it compound?  

d) What is the interest rate per compounding period?      r

e)  What is the total number of time period   n

Thanks.... but I seriously hope you have learned how to do it yourself next time.

Just substitute 800 for x.

There might be or there might not be.

Maybe your question is, "What is the probability that there will be 3 consecutive numbers roll"

But even that would not be clear enough. 

Do the three numbers have to be rolled in a row?

Would  1,6,3,2,6 be alright since it has a 1,2, and 3?

You need to ask a very precise question.

You have to look carefully at the logic.

If you are late up, you will miss the bus   That is stated.

If you are not late up, will you catch the bus?  Maybe, maybe not, there is no logically statement about what will happen if you get up early.

Now use that logic to work out which statement must be true.  There is only one.  

Your question does not make sense.

In your original question, you said it was per week.  

In the second attempt at writing the question you said per day.

Please be careful to proofread.

Here is your graph.

The break-even number of sales for a day/week  is 153 burgers. (read from the graph)

But 450 burgers are sold. 

That amounts to an income (revenue) of 7.5*450 = $3375

And a cost of  0.45*450+1077.5 = 1280

Profit = 3375-1280 = $2095

Asker can you please tell me what complimentary means?   Do you know?

If you don'r know then look it up.

Either way please answer my question.

Use desmos to graph your function and look at it.

Your right, there is no intersection at x=450.

I only point it there because it is a point mentioned in the question.

v does stand for something, it stands for the income function.

the intersection of the two can be read of my graph.

(But I still do not understand the question properly.)
