Tammy completed 12 jobs.
<h3>What is the substitution method?</h3>
The algebraic approach to solving simultaneous linear equations is known as the substitution method. in this procedure, The value of one variable from one equation is substituted in the second equation.
Given Susanne(S) did 10 jobs, and three girls together did 28 jobs Tammy(T) works twice as fast as Martha(M).
Since the girls each worked for two hours, this indicates that Tammy worked twice as much or held twice as many jobs.
T = 2M ........................equation (1)
M + S + T = 28 ........................equation(2)
S = 10 ..................................equation(3)
By solving the above equation, we get:
Martha(M) = 6
Tammy(T) = 12
Hence, Tammy completed 12 jobs.

Explanation:
To begin with, the term called<em> ''stuck in the middle''</em> is known in the business world for the main reason of <em>being stuck in a situation where the costs of the firms are to high</em> to allow them to have competitive and attractive prices and and that also<em> these companies do no differentiate their product enough</em> in the way to generate value to the customer they want to reach and therefore it is said that these firms are stuck in the middle due to the fact that <u><em>they can not improve their benefits</em></u> because of their high cost structure and low differentation.
