x the number of yellow
$13.50x + $9.95(17-x) = $211.75
x = (211.75-17•9.95)/3.55 = 12 the number of yellow. White: 5
And...checking
12•$13.50 + 5•$9.95 = 211.75
Will Leave the checking calculation to You.

Let W = number of White shirts
Let Y = number of Yellow shirts
Since we have two variables, we need two equations.
Equation 1:
Equation 2:
---------------------------------------
Start by solving equation 1 for one of the variables
Equation 1:
Plug (17-Y) into equation 2 for W
Equation 2:
Simplify
Combine like terms
Subtract 169.15 from both sides
Divide both sides by 3.55
------------------------
Using Y=12, solve for W
