Answer:
Value of the stock traded was $5200.
Step-by-step explanation:
In this question it is given that trading company charges commission of $10 per trade or transaction plus $.025 per dollar value of stock.We have to calculate the value of stock we traded if total commission (commission on trade value + commission on trade) is $140.
Let the value of stock traded was $x.
Then commission on value of the stock = x×.025
Commission on transaction = $10
Total commission = 140 = ( .025x + 10)
⇒.025x = 140-10 = 130
x = 130÷.025 = $5200
So the value of the stock = $5200
