Giovanny Davies · Answer 1

The total cost for the entire life span of the deep fryer is computed below:

Brand P total cost = Purchase price + total electricity cost

= $144 + ($0.49x8x12x6)

=$426.24

Brand Q total cost = (Purchase price x 3) + total electricity cost

= ($37.5x3) + ($0.75x 8x12x6)

= $544.5

Difference = Brand Q-Brand P

=$544.5-$426.24

=$118.26

Robert will have to choose Brand P because it will be cheaper by $118.26 than Brand Q in their entire lifetime.
