D) $W = 12.25 x - 0.3$
E) $W = 12.55 x$

Quizplus · Accepted Answer

The hourly wage W consists of a fixed hourly rate ($12.25) plus a variable piecework rate ($0.3 per unit), so the equation is $W = 0.3x + 12.25$, where x is the number of units produced per hour.

A Microchip Manufacturer Pays Its Assembly Line Workers $12 W=0.3x+12.25W = 0.3 x + 12.25W=0.3x+12.25

A Microchip Manufacturer Pays Its Assembly Line Workers $12 $W = 0.3 x + 12.25$
