If you multiply 12 by 0.1, you get 1.2. To write this as a function you would say y is x multiplied by 0.1.
y=0.1x
To answer the problem given above, divide the difference of the prices by the original price and multiply the answer by 100%. This is,
((22450 - 19450) / 19450) x 100% = 15.42%
Therefore, the percentage markup of the new car is approximately 15.42%.
5-1 x 20=56/56 x 90/56 54/67=67
So you follow the steps and i hope this will be easy for you .
PEMDAS
(3+2)=5
(5-1+2)=6
6*5*4=120
