Use an appropriate physical model for subtraction to solve each of the following problems. Explain your reasoning for choosing each model.
Sneha has assembled

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

Steel Production is related to the amount of labor used(L) and the amount of capital used ( C ) by the following function:S = 20L⁰˙³⁰C⁰˙⁷⁰In this formula L represents the units of Labor input and C the units of Capital input. Each unit of Labor costs $50, and each unit of Capital costs $100. a:Formulate an optimization problem that will determine how much labor and capital are needed to produce 50,000 tons of steel at minimum cost.
