Answer:

200 %

Step-by-step explanation:

From the question above, the pencils increases from 75 to 225, so what we are looking for is the percentage increase

The formula for finding percentage increase is;

% increase = $\frac{Increase}{Original}$ × 100%

First; we will find the difference between the two numbers i.e 75 and 225

Increase = New number - Original number

= 225 - 75

= 150

Then we divide the increase by the original number and then multiply by 100 %

That is;

% increase = $\frac{150}{75}$ × 100%

= 2 × 100%

= 200%

Therefore; the percentage increase is 200%

For finding percents, I use a method called FOO
which is final-original÷original
the original is the first number and the final is the second
After FOO you must multiply by 100 to make it a percent
The equation is as followed:
225-75÷75×100
The answer is 125%

Answer:

2. B

3. C

4. B

5. D

Step-by-step explanation:

2) The sequence is multiplying by -2 each time. This means that it is geometric.

The next two terms would be:

$32*-2=-64\\-64*-2=128\\128*-2=-256$

This means that the answer is B

3) The sequence is being multiplied by $\frac{1}{3}$ each time. This means that it is geometric.

The next 3 terms would be:

$3*\frac{1}{3} =1 \\\\1*\frac{1}{3} =\frac{1}{3} \\\\\frac{1}{3} *\frac{1}{3} =\frac{1}{9}$

I am assuming that the answer is C and that you were unable to type the fractions.

4) We know that the common difference is 1.5, so that is the coefficient of our variable and the starting value is 15. This means that we can write an equation as follows

$f(x)=1.5(x-1)+15$
