The school band is selling sweatshirts and baseball caps to raise $9000 to attend a band competition. Sweatshirts cost $25 each and baseball caps cost $10 each. The equation 25x + 10y = 9000 models this situation, where x is the number of sweatshirts sold and y is the number of baseball caps sold.

If 258 sweatshirts are sold, how many baseball caps are sold?
