There are 21 boxes of crackers in 1 case. Each box contains 24 crackers. What is the best estimate for the number of crackers in 7 cases?
A. 3,100
B. 3,500
C. 3,800
D. 4,000
Do I do 24x21? If I'm suppose to do that I don't know what I'm suppose to do next
It's B,right?
Right!
Instead of 24x21 I do 20x25?
Yes, multiply 20 * 25 * 7
To find the best estimate for the number of crackers in 7 cases, you can start by finding the number of crackers in one case and then multiply it by 7.
In this case, each box contains 24 crackers, and there are 21 boxes in one case. So, to find the number of crackers in one case, you can multiply 24 by 21:
24 x 21 = 504 crackers in one case
Now, to find the best estimate for the number of crackers in 7 cases, you can multiply the number of crackers in one case by 7:
504 x 7 = 3,528
Therefore, the best estimate for the number of crackers in 7 cases is 3,528.
From the given options, the closest estimate to 3,528 is option B, 3,500.
You're partly right. Now you need to multiply by 7.
Since you're supposed to estimate, multiply 20 * 25 * 7
