In order to keep the constant, the same and not vary there must be an indirect or inverse relationship to always maintain the value of k.

Thus both P and V are inversely related to each other.

I think the answer to this is: 25q + 10d + 5n + 60 = 87

The story says that you have 1 dollar and 87 cents; 60 cents of which is pennies. So, if you’re using an equation involving quarters, dimes and nickels, the total equation should equal to 87 cents (since that dollar bill could not be broken down to cents).

Lana71 [14]
The answer is 1.25 hours.

STEP 1.
Each page has about 350 words:    1 page - 350 words
15 pages is x words:                         15 pages - x words
1 : 350 = 15 : x
x = 15 * 350 : 1 = 5250

So, she has to type at least 5250 words.

STEP 2:
<span>Stephanie can type around 70 words per minute:     70 words - 1 minute
x words in 1 hour = 60 minute:                                        x words - 60 minute

70 : 1 = x : 60
x = 70 * 60 : 1 = 4200

So, she types around 4200 words per hour.


STEP 3:
Now we have:
</span>- she has to type at least 5250 words
- she types around 4200 words per hour

5250 : x = 4200 : 1
x = 5250 * 1 : 4200 = 1.25 hours
