Sneha has assembled
![Check Mark](/static/check-mark.png)
The number of components that Sneha must assemble to reach her quota. Where, Sneha has assembled
Answer to Problem 1GA
Solution:
The number of components that Sneha must assemble to reach her quota is
Explanation of Solution
Given information:
Sneha has assembled
Explanation:
As there is need to find the number that must be added to
To find the number of components that Sneha must assemble to reach her quota mean to find
For this find the number that must be added to
Therefore, the appropriate model of subtraction is Missing Addend Model.
Start with
Continue adding computer components:
Therefore
Hence, the number of components that Sneha must assemble to reach her quota is
