I believe the answer is 10,
3-1=2+15=17-7=10

Answer: Jimmy has 10 balls .

Step-by-step explanation:

Since we have given that

Number of balls Jimmy has = 3

Number of lost balls = 1

Remaining balls Jimmy has = 3-1=2

Number of balls Earl gives to Jimmy = 15

Now,

Total Number of balls Jimmy has = 15+2=17

Again,

Number of balls Jimmy lost = 7

So,

Remaining balls Jimmy has = 17-7=10

So, he has 10 balls at last .
