Answer:
Step-by-step explanation:
Let the rate of commission is x%.
<u>Total earning is:</u>
- 7500 + 120000*x/100 = 13500
- 1200x = 13500 - 7500
- 1200x = 6000
- x = 6000/1200
- x = 5
Answer:
b. When you divide both sides by 2x = 6x it could lead us to think that there is no solution while, in fact, the solution is x = 0.
Step-by-step explanation:
The solution is correct up to the step 2x = 6x
2x = 6x
Subtract 2x from both sides.
0 = 4x
Divide both sides by 4.
x = 0
You cannot divide both sides by x since x could be zero, and in fact, it is.
Answer: b. When you divide both sides by 2x = 6x it could lead us to think that there is no solution while, in fact, the solution is x = 0.
