Expert Solution & Answer
Chapter 7.1, Problem 58E
Solution
a.
To calculate: The number of Stephanie’s weekly sales be to earn the same amount on the two plans.
Stephanie makes $7500 in sales she would earn $675 with either plan.
Given Information:
The statement are defined as,
Plan A: a $300 weekly salary plus 5% of her sales.
Plan B: a $600 weekly salary plus 1% of her sales.
Calculation:
Consider the given statements,
Suppose that the number of Stephanie's sales is
Convert the given statements to in equation form.
Plan A: a $300 weekly salary plus 5% of her sales.
Plan B: a $600 weekly salary plus 1% of her sales.
Now solve both equation by equating each other to equal.
Now, find the value of
Therefore, Stephanie makes $7500 in sales she would earn $675 with either plan.
b.
To determine: The reason to choose one plan over the other by Stephanie.
Stephanie should choose plan A due if she can sell more than $7500.
Given Information:
The statement is “Give reasons why Stephanie might choose one plan over the other. Explain.”
Calculation:
Consider the given statements,
Refer both the equation.
And,
Stephanie should base her decision on how much she thinks she can sell. If she thinks she can sell more than $7500 she should pick Plan A.
Therefore, Stephanie should choose company A.
