Q. The lacrosse team sold ss team booster sweatshirts, and 1919 of them were adult sizes. Choose the expression that shows how many sweatshirts were not adult sizes.\newlineChoices:\newline(A) s+19s + 19\newline(B) 19−s19 - s\newline(C) 1919\newline(D) s−19s - 19
  1. Define Total Sweatshirts: Let's call the total number of sweatshirts sold 'ss'. We know that 1919 of these are adult sizes. So, the number of sweatshirts that are not adult sizes would be the total 'ss' minus the 1919 adult sweatshirts.\newlineCalculation: s−19s - 19
  2. Calculate Non-Adult Sweatshirts: Now, let's check the choices to see which one matches our calculation.\newline(A) s+19s + 19 (No, this would mean we're adding more sweatshirts.)\newline(B) 19−s19 - s (No, this would mean we started with 1919 and sold some, which doesn't make sense.)\newline(C) 1919 (No, this is just the number of adult sweatshirts.)\newline(D) s−19s - 19 (Yes, this matches our calculation.)
