Question 681787
Take 40% of 67.50 to get 0.4*67.50 = 27


So 40% of $67.50 is $27.


Add this to the original amount ($67.50) to get 


67.50 + 27 = 94.50


=======================================================


Doing it in general


If you want to add 40% to any amount, call it x dollars, then


take 40% of x to get 0.4x


Then add it to the original amount x to get x + 0.4x


You can combine like terms to get 1.4x


Notice how 1.4 times 67.50 gives you the same answer as before.
