The price of a certain painting increased by 20% during the first year and decreased by 15% during the second year. The price of

Rina8888 [55]

Answer:

A.102%

Step-by-step explanation:

Let cost price of painting=$100

In first year price increased 20%

Then , the price= $100+100(0.20)=$ $120

In second year

Price decreased 15%

Then , the price of painting= $120-120(0.15)$

The price of painting=$102

Percent = $\frac{final\;price}{Initial\;price}\times 100$

By using this formula

Then, we get

Percent of the original price= $\frac{102}{100}\times 100$

Percent of the original price=102%

Option A is true.

The function y = 4x + 3 describes Player A's

anyanavicka [17]

The rates of change of points earned by both players tell us that;

Player A gains more point than Player B does for each correct answer in this round.

We are told that x is the number of

number ofquestions answered correctly and y is the score.

Now, for player B;

For 1 correct answer, he got a score of 4

For 2 correct answers, he got a score of 5

For 3 correct answers, he got a score of 6

For 4 correct answers, he got a score of 7

This means that rate of change of Player B is;

3 points for every extra question answered correctly. .

Now, the formula for player A's points is;

y = 4x + 3

Rate of change of points here is gotten by finding the derivative. Thus;

dy/dx = 4

This means player A earns 4 points for every extra question answered correctly.

In conclusion, it mean that Player A gains more point than Player B does for each correct answer in this round.

the ratio of rock music total cds that ella owns is 25/40 .paolo has 59 rock music cds.the ratio of rock music to total cds in h

const2013 [10]

So, the given information tells us that the ratios between ella's rock music to total cds and paolo's rock music to total cds is the same. This means that we can set them up in a proportion equal to each other. (Let x represent the amount of total cds in paolo's collection)

25/40=59/x

Next, to simplify this equation, we need to use cross-products to cancel out the fraction bars.

25 59
=
40 x

If done correctly, the resulting equation is 20*x=59*40

When simplified, the resulting equation is 20x=2360

Finally, we need to divide both sides by 20, in order to find out what integer represents x in this equation.

x=118

This means that Paolo has a total of 118 cds in his collection.

The question asks how many CDs Paolo and Ella own together. To figure this out, all you need to do is add how many CDs Ella has (40) to how many CDs Paolo has (118).

40+118=158.

Paolo and Ella's combined collection of total CDs is 158 CDS.
