Question

Kevin is looking at two brands of washing machines. Between water and electricity, a Brand C washer uses about $0.65 per load, and a Brand D washer uses about $0.27 per load. Kevin averages about five loads of laundry per month. After one year, how much more would the utility costs for a Brand C washer be than the utility costs for a Brand D washer?
a.
$22.80
b.
$16.20
c.
$7.60
d.
$19.00

Answer 1

Brand C costs $0.65 - $0.27 = $0.38 more per load.
At 5 loads/month that's $0.38 × 5 = $1.90 more per month.
Over 12 months: $1.90 × 12 = $22.80.

Answer: a. $22.80
