Question

The Kendal Company manufactures automobile engine parts. Running the manufacturing operations requires 12 watts (units of electricity per hour). The amount of electricity required to run the manufacturing operations and lighting the facility is given by y = 12x + 24, where x is the number of hours of manufacturing and y is the amount of electricity expended. How much electricity is used on a day when no parts are

Answer 1

24 because when you plug in 0 for both x and y:  

0=12(0)+24  

12*0=0, leaving you with 24.
