Answer:

-20%

Step-by-step explanation:

We have to Harry bought a quantity of fruit.

He sold half, that is 50% but I earn 60%, that is to say that here he made 10% of profits.

Then he sold 1/4 of the total, that is 25% but he took 20% of profits, that is to say that in this case he obtained 5% of losses.

They tell us that the rest was spoiled, that is, 100 - 50 - 25 = 25% was spoiled, and all that is lost, in the end the balance is as follows:

10% - 5% - 25% = -20%

That is to say that in general it lost 20% of the total.

Answer: 35%

Step-by-step explanation:

Let the original price be "4x".

60% gain on 1/2 of them will be:

(1.60 × 2x) = 3.2x - 2x = 1.2x

20% gain on (1/4) of them will be:

(1.2 × x) = 1.2x - x= 0.2x

Total gain 1.2x + 0.2x = 1.4x

Total gain percent= Gain/Original price =1.4x/4x = 0.35 = 35%

The opening balance of the January billing cycle for Megan's credit card was $4,805 if she makes a new purchase of 300 on the 20
Nookie1986 [14]

Answer:

$4911.45

Step-by-step explanation:

To find Megan's average daily balance, we first need to assume that the billing cycle begins at January 1st.

Now we know that there are 31 days in the month of January, we will use that as our basis.

20 days x 4805 = First 20 days of the billing cycle.

11 days 4805 + 300 = 21st day of the billing cycle.

31 days in the month

So now we simply add the first 20 days and the days after the 21st day and divide it by the number of days in the month since we're looking for the average.

(20 x 4805 + 11(4805+300))/31

(20 x 4805 + 11(5105))/31

(96100 + 56155)/31

152255/31

This then gives us:

$4911.45

Let f(x)=g(x)h(x), g(10)=-4, h(10)=560, g'(10)=0, and h'(10)=35. find f'(10)
Ulleksa [173]
This question has extraneous info to trick you.
f(x) = g(x)h(x) ⇒ f'(x) = g'(x)h'(x) . Letting x = 10, we get f'(10) = g'(10)h'(10). then just plug in the values provided. g(10) and h(10) are there to throw you off, just use g'(10) and h'(10).
So f'(10), pronounced "eff prime of ten", = 0 * 35 = 0.

If the question were asking for f(10) instead of f'(10) then you would use g(10) and h(10), ⇒-4*560=90.
