After the first week of the fundraiser, they sold StartFraction one-third EndFraction of the short-sleeved shirts and StartFraction one-half EndFraction of the long-sleeved shirts, for a total of 100 shirts. This system of equations models the situation. 5x + 10y = 1,750 x + A system of equations. 5 x plus 10 y equals 1,750. StartFraction one-third EndFraction x plus StartFraction one-half EndFraction y equals 100.y = 100 Let x represent the number of short-sleeved shirts ordered and let y represent the number of long-sleeved shirts ordered.
