A banker’s compensation consists of a weekly salary as well as a commission for each account opened. The banker earns commission at a rate of $10/account. In one particular week, the banker opened 15 accounts and brought home a total pay of $830. Which of the following equations describes the pay for the banker in terms of accounts opened? A. y = 10x + 15 B. y = 10x + 68 C. y = 15x + 680 D. y= 15x + 830

Respuesta :

B. y = 10x + 680 

Breakdown: 

he bring a total of $830 home 
he opens 15 accounts at $10/account 
he has an unknown amount of salary. 

Hence to determine the salary, Subtract the commission of the opened accounts from the total he brings home i.e. 

830 = Salary + Commission (rearranging gives) 

Salary = 830 - Commission (but Commission = 15*10 = 150) 

Salary = 830 - 150 = 680 

Therefore his pay structure is of the form 

Y = 680 + 10x, where x is the number of accounts opened 

Hope that helps

y = 15x + 680 describes the pay for the banker in terms of accounts opened.
