ashley would like to reduce her impact on the environment. to do this, she decides to install a solar water heater, like the one
shown in the image below, on her home. this type of heater captures the thermal energy from the sun and uses it to heat water
for a home.
ashley wants the water heater to provide enough hot water for all four members of her household every day, which would need to
be about 75 gallons. she has a budget of $3500 and her home receives about six hours of direct sunlight each day.
the table below shows information about four different solar water heating systems. which brand would best meet ashley's
criteria and constraints?
