Answer: Our required equation will be 
Step-by-step explanation:
Since we have given that
Base salary of Karen = $2000
Rate of commission on all of her sales = 20%
We need to write a equation:
Let the total salary of her be 's'
Let the number of dollars of merchandise sold be 'd'
According to question, it becomes

Hence, our required equation will be 
Suppose A equals 10. Lets use 20% of 10, or 2.
10/2 = 5.
As we can see, the equations varies depending on the percentage used. We can effectively conclude that:
A/(1/5A)
5A.
The equation is equal to the reciprocal percentage times A.
Another example:
50 divided by 10% of 50 (5).
50/5 = A
50 * 1/5 = A
10 = A
C. i have only seen this method on checks
Answer:
D. 8.8
Step-by-step explanation:
As the pythagorean theorem.
A² + B² = C²,
5.4 × 5.4 + 7 × 7 = C²,
29.16 + 49 = C²,
78.16 = C²,
8.8 ≈ C
Answer:
A.
