Word Problem

These questions are from millions of online tutorials and YouTube websites. I don’t know if I am allowed to ask experts to explain those questions in a different way. They are not homework assignments. I am trying to develop my own web site. Math’s has many ways to solve the problems. Just want to understand them.

1. In part B according to my calculation, 20% of 84 is 16.8 and then subtract 16.8 from 84 to get the whole sale price which is 67.2 but the correct answer is $70.

first of all, please allow me to ask you to refer to this type of problem as a MATH problem

in this forum, it is generally understood by 'Word problem' that you are having problems with Microsoft Word...  very confusing

that being said, you have to realize that the final price of a product in this problem is

wholesale + 20% of wholesale = retail

you know the RETAIL price...

so: wholesale (1.2) = 84$

wholesale = 84$/1.2

wholesale = $70

84 is 120% as Statement stated that Retail Price is 20% more than whole sale price. So considering retail price 84 i.e 120% ...you just need to find 100% of 84......excel calculation =(84*100%)/120%
