I’m pretty sure it’s C. because half of 12 is 6 so if they’re buying a pound and a half it would be 12+6, which is 18
19 - 4 = 15 baskets made in those last three games. If the same number of baskets were made in those three games, she made five in each game, because 5 + 5 + 5 = 15 (the number of baskets made in those final three games). Thus 5 baskets per game is the answer. Hope this helps!
