4) Harold has been hired as a salesman. He is paid a flat rate of $375 each week and earns an additional $14.25 commission for each sale. If x represents the number of sales and y represents the total earned, which equation will help Harold determine the amount he earns in one week?
y = $375h – $14.25
y = $375h + $14.25
y = $14.25h + $375
y = $14.25h – $375
I said y = $14.25h + $375
