All we have to do is divide how many blueberries he ate in an hour (80) by how many times 15 minutes is in 1 hour (4)
80 ÷ 4 = 20
We can check our work by multiplying 20 by 4
20 x 4 = 80
Therefore, David ate 20 blueberries in 15 minutes
Hope this helps you!
Always remember you are a Work Of Art!

whats ur question about it?
Answer:
There were 261 Cheeseburgers and 87 Hamburgers sold on Tuesday
Step-by-step explanation:
Lets write some equations where H=Hamburgers and C=Cheeseburgers:
1) H+C=348
2) C=3H
1) Substitute 3H as C in the first equation:
3H+H=348
2) Combine alike terms:
4H=348
3) Divide both sides by 4:
H=87
4) Now, substitute 87 as H in the first equation:
87+C=348
5) Subtract 87 from both sides:
C=261
Answer: 4
Explanation:
Given that 3x−y=27, 3x+y=243
⇒3x−y =33 , 3x+y=35
=> x-y=3, x+y=5
=> x = 4
