Pls me with this asap (show work + correct answer pls) lots of

First, let's find the total price before tax.  We do this by adding up the two shirts that are priced normally.  This is 49.96+49.96=99.92.  Now, we add half of 49.96 to 99.92.  



Now, we find what 7.1% of 124.90 is.  We do this by doing this:



Now, we solve for x by multiplying both sides by 124.90.



This is what the tax is.  To find how much all of the shirts cost together, we add 8.87 to 124.90.  This is equal to 133.77.  Now, we divide 133.77 by 3 to find the mean cost of the shirts.  This is equal to 44.59.

So the answer is C, $44.59.
