You have just moved into a new house and need to purchase a washing machine. Front-
loading machines use less water but that they are more expensive.
A top-loading machine
costs $500
and a new front-loading washing machine costs
$1,000.
(a) If you wash 8 loads of laundry each week, how many loads do you wash each
month (assume 4
weeks/month)?
(b) If the top-loading machine uses 200L of water per load and the front-loading
machine uses 100 L of water per load, how many liters of water would the
front-loading washing machine save per month?
(c) If water costs $0.35 for every 1,000L, how much money would be saved each
month by using the front-loading washing machine?
