Sagot :
Clearly, alternative B
y = 0.01x + 7.5
y = (0.01)*5000 + 7,5
y = 50 + 7.5
y = 57.50
y = 0.01x + 7.5
y = (0.01)*5000 + 7,5
y = 50 + 7.5
y = 57.50
Answer:
Option B. y = .01x + 7.5
Step-by-step explanation:
If a stock broker earns a commission by a flat fee for each transaction as well as a fee per share.
Let the commission on each share charged by the stock broker is x.
Selling price of 5000 shares + total fees of broker = Cost of the transaction
5000×.01 + Fees = 57.50
Fees = 57.50 - 50 = $7.50
Now we can form the equation which represents the cost of this transaction as
y = .01x + 7.5
Therefore option B is the correct answer.
