Answer: 100 cookies approximately.
Step-by-step explanation:
To round to the nearest ten:
- If the digit located in the units place of the number is [tex]<5[/tex], then you must round the number down.
- If the digit located in the units place of the number is [tex]\geq5[/tex], then you must round the number up.
The digit located in the units place of the number 11 is 1 and [tex]1<5[/tex], therefore you must round the number down to: 10
The digit located in the units place of the number 12 is 2 and [tex]2<5[/tex], therefore you must round the number down to: 10
Multiply 10 by 10 to estimate the total number of cookies:
[tex]Total_{(cookies)}=10*10\\Total_{(cookies)}=100[/tex]
(100 cookies approximately)
