Styline menswear ordered short-sleeve shirts for $23 each and long-sleeve shirts for $28.50

short-sleeve shirts for $23

long-sleeve shirts for $28.50

Total cost = $9,862.50

Let x be the number of short - sleeve

and y be the number of long - sleeve

Total shirts = 375

x + y = 375

23x + 28.50y = 9862.50

Now we solve for x

x + y = 375 (subtract x on both sides)

So y = 375 - x

Now plug in 375 - x for y in second equation

23x + 28.50y = 9862.50

23x + 28.50 (375 - x) = 9862.50

23x + 10687.5 - 28.50x = 9862.50

subtract 10687.5 from both sides

23x - 28.50x = - 825

-5.5x = - 825 (divide - 5.5 on both sides)

x = 150

So number of short-sleeve = 150
