Uncle Li brings 100 yuan to the store to buy a football and a volleyball. There are two kinds of footballs with unit prices of 48 yuan and 56 yuan respectively, and three kinds of volleyballs with unit prices of 44 yuan, 38 yuan and 50 yuan respectively. May I ask how many ways Uncle Li can buy at most? (No need to calculate, simply state the reason.)
