Answer:

$339.84

Step-by-step explanation:

Consumption per day in kilowatt-hour will be given by

24*1475/1000=35.4 kwh

Consumption per month will be

35.4*30=1062 kwh

For 4 months, electrical consumption will then be

4*1062=4248 kwh

Consumption in terms of money, considering the rate of $0.08 per​ kilowatt-hour

4248*0.08=$339.84

Therefore, the spa will pay $339.84
