Question

MATH HELP PLZZZ 20 POINTS!!!!!

Answer 1

a)
Game 1 = 180

Game 2 = 200

Increase = 200 - 180 = 20

% Increase : Mind you the baseline for division or reference is the 180 and not the 200. The first one between the two numbers is the reference.

So % Increase = (20 / 180) * 100%

= (1/9) * 100% = 11.11%

Increase = 11.11%

b)
Game 2 = 200

Game 3 = 180

Decrease = 200 - 180 = 20

% Decrease : Mind you the baseline for division or reference is the 200 and not the 180. The first one between the two numbers is the reference.

So % Increase = (20 / 200) * 100%

= (1/10) * 100% = 10%

Decrease = 10%

Answer 2

Number 1.) In game 1 he scored 180 points, In game 2 he scored 200 points this means the score went up , so now you have to add, ( Addition ).

180 + x = 200 | x=? , well 180 + 20 = 200.


Since there is 20 points added to 180 which gives us 200 there is an 11.11% increase .
__________________________________________________



Number 2.) , In the next game he scored 200 points , it asks what is the decreased number?

how many numbers did his score drop? 200 - 180 = 20 |


Now we must work backwards , There is a loss in points , ( 20 ) , so there is an 10% decrease.
(200-180) / 180 * 100% = 10%

20 / 200 * 100% = 10%

20 = The Answer with an 11.11% increase , there is a 10% decrease.

I hope this helps you a lot
