To find out the cost of running the fan for 6 hours, we can set up a proportion. Let's call the cost of running the fan for 6 hours "x":
4 hours / $0.60 = 6 hours / x
To solve this proportion, we can cross-multiply:
4x = 6 * $0.60
4x = $3.60
Divide both sides of the equation by 4:
x = $3.60 / 4 = $0.90
Therefore, it would cost $0.90 to run the fan for 6 hours.
4 hours / $0.60 = 6 hours / x
To solve this proportion, we can cross-multiply:
4x = 6 * $0.60
4x = $3.60
Divide both sides of the equation by 4:
x = $3.60 / 4 = $0.90
Therefore, it would cost $0.90 to run the fan for 6 hours.
