The drama club is selling short-sleeved shirts for $5 each, and long-sleeved shirts for $10 each. They hope to sell all of the shirts they ordered, to earn a total of $1,750. After the first week of the fundraiser, they sold of the short-sleeved shirts and of the long-sleeved shirts, for a total of 100 shirts. Let x represent the number of short-sleeved shirts ordered and let y represent the number of long-sleeved shirts ordered. Which system of linear equations represents the situation? 5x + 10y = 100 and x + y = 1,750 5x + 10y = 1,750 and x + y = 100 x + y = 100 and x + y = 1,750 x + y = 1,750 and x + y = 100
