Ответ:
0 hot items and 11 cold items
Step-by-step explanation:
He has 25 dollars to spend.
Hot: 3
Cold: 2
Let's eliminate some wrong answers.
1. 0 hot items and 11 cold items: Possible, because 11 times 2 is 22.
2. 9 hot items and 1 cold item: Impossible, because 9 times 3 = 27 and that is already over 25 dollars. This one is eliminated.
3. 2 hot items and 8 cold items: 2 times 3 is 6. 8 times 2 is 16. 16 + 3 = 19. He buys 10 items here. Selection one bought 11 items though, so this one is eliminated.
4. 6 hot items and 4 cold items: 6 times 3 is 18, and 4 times 2 is 8. 18 + 8 = 26. He doesn't have enough money, so this one is eliminated.
