We have been given that a retailer buys cases of 24 shirts for $30/case and then resells them in packs of 5 for $8/pack.
Further, we know that retailer sold all the shirts he purchased and profited $84 on the sale.
Let us first find LCM of 24 and 5. The LCM is 120.
Now, let us assume that the retailer bought 120x shirts. Therefore total profit will be:

We can set this equal to the given profit to figure out the value of x first.

Therefore, the retailer sold 120(2)=240 shirts, that is, 48 packs.
4.5 because 1/2 equals .5 and 4 equals for
add 14+8 first, which is 22
then, multiply 6 by 22, which is 132
and lastly, add 12
the answer is 144
If x=3 then 5x3=15-2=13+6=19x1/4=4 3/4 so that means that 2 1/4+2 1/2 could be equivalent
P.S.I just chose 3 because it was the first number to pop into my head
