Answer: Yes, he can buy 20 putters.
Step-by-step explanation: The inequality to solve this question is:
6.30.x + 10.95.y ≤ 300
As x = 10, it will be
6.3.10 + 10.95.y ≤ 300
10.95.y ≤ 300 - 63
10.95.y ≤ 237
y ≤ 22
Now, as the quantity of putters the owner has to buy to meet his budget is less or equal 22, the owner can buy 20 putters.
