Hi,

It is quite straightforward forward and you can do it in two ways..
1) Algebraic..
100 for X but sold for 50..
Thus overall profit is (50-x)..
But we are looking for profit per piece = $$\frac{50-x}{100}=0.5-\frac{X}{100}$$
E
2) substitute a value for X
Let X = 40
So profit = 50-40=10
Per piece = 10/100=0.1
Only E gives you 0.1 as answer 0.5-40/100=0.5-0.4=0.1
E

Re: A clothing store bought 100 shirts for $x. If the store sold [#permalink] 10 Oct 2020, 04:45 1 This post received KUDOS The question asks for store’s profit per shirt We have Cost Price of 100 shirts = x, so Cost Price of 1 shirt = x/100 Now, Sell Price of 100 shirts =$50, so Sell Price of 1 shirt = 50/100

Profit (in dollars)= S.P. - C.P. = 50/100 - x/100 => 0.5 - x/100.
