mote1985 [20]

Step-by-step explanation:

1.

1% of 500 is 5 so multiply 5 by 8 for one year. which is 40 so multiply that by 2.

1% of 500 = 5

5 × 8 = 40

40 × 2 = 80

2.

1% of 1000 = 10

10 × 5 = 50

50 × 3 = 150

3.

12 months = 6%

6/12 = 1 month

0.5 = 1 month

0.5 × 9 = 4.5 (the amount of interest for 9 months.)

800 × 4.5% = 36

4.

12 months = 7%

7/12 = 1 month ( i'll leave this in fraction form because of the decimal points.)

7/12 x 8 = 4.666667 or 4.7 rounded.

1200 × 4.7% = 56.40

ra1l [238]

The sets can either be presented in set builder form or roaster form. The

given sets presented in the required form are;

a. The set B is the set of days in the week that starts with letter S

Therefore;

The elements of B are; Saturday, Sunday

In roster method, we have; B = {<u>Saturday, Sunday</u>}

In set builder notation, we have; B = {<u>x | x is a days in the week that starts with letter S</u>}

b. C is the set of letters in PHILIPPINES

In roster form, we have; <u>C = {P, H, I, L, I, P, P, I, N, E, S}</u>

In set builder notation, we have; <u>C = {Letters in the word PHILLIPINES}</u>

ANSWER


ANSWER TO QUESTION 1.

If you give x surfing lessons, then you will earn $ 25x


If you are charged $200 for using the place, then your profit will reduce by $200.


The profit function is given by


P(x)=25x-200 dollars.


The y-intercept is  -200. It is negative because it is a cost which is a liability. So it does not add to your profit.


ANSWER TO QUESTION 2.

The slope is 25. It is positive because as the number of hours increases, the profit earned also increases. In other words there is a direct relation between the number of hours worked and the profit earned.



ANSWER TO QUESTION 3.

The slope intercept form is when an equation is written in the form;

y=mx+c,


where m is the slope and c is the y-intercept. The profit function in slope intercept form is

P(x)=25x-200


ANSWER TO QUESTION 4.

If you break even, then the difference between the revenue and cost is zero. So we equate the profit function to zero.


25x-200=0



25x=200


x=8


Therefore you need to give 8 different lessons to break even.


ANSWER TO QUESTION 5.

If you give 20 lessons, the x=20. We need to substitute


x=20 in to the profit function to calculate the profit made after 20 lessons.

P(20)=25(20)-200


P(20)=500-200


P(20)=300.


ANSWER TO QUESTION 6.

If the new price is $75, then the new profit function becomes


P(x)=75x-200


ANSWER TO QUESTION 7.

To find the number of lessons that lets you break even, we equate the new profit function to zero.

75x-200=0

We solve for x by adding 200 to both sides of the equation.



\Rightarrow 75x=200

We now divide through by 75

\Rightarrow x=\frac{200}{75}


\Rightarrow x=2\frac{2}{3}


Therefore you would have to 2\frac{2}{3} lessons to break even. That is approximately 3 lessons.


ANSWER TO QUESTION 8.

If you give 20 lessons and we want to find the profit you made with this new profit function, then we have to plug in x=20 in to P(x)=75x-200.


That is,


P(20)=75(20)-200


P(20)=1500-200


P(20)=1300 dollars
