Steve,
#1  forget about the blue pencils. There are 8 yellows in each package. So, in 426 packages, there are 8*426=3408.
Note that the title of the problem set was "Multiply a 3 digit number by a 1 digit number". That should have been a clue that your approach was wrong.
#2  multiply and check:
3*616 = 1848
4*616 = 2464
5*616 = 3080
So, which is closest to 3000?
#3
So, whatcha think? Are 2250 erasers enough for 3000 pencils? 
Math 
Ms. Sue,
1. Why did you multiply by 4? You only need to find the total of yellow pencils.
2. 3000 / 616 = ?
3. Right.
