Answer:
300
Step-by-step explanation:
(-3)(-100)= -3 x -100
A NEGATIVE MULTIPLIED BY A NEGATIVE WILL ALWAYS GET A POSITIVE SO MAKE -3 INTO 3 AND TURN -100 INTO 100.
Now you have 3 x 100 which gets you <u>300</u>
To increase a umber by a certain percent, you imagine 100% as 1 then if you want to increase by x% you times your original number by (1+x) e.g. increase 25 by 13%
x=13
25 × 1.13 = 28.25
