Lee watches TV for 2 hours per day. During that time, the TV consumes 250 watts per hour. Electricity costs (10 cents)/(1 kilowatt-hour). How much does Lee's TV cost to operate for a month of 30 days?

The total cost to operate Lee's TV for a month of 30 days is 150 cents and this can be determined by using the given data.

Given :

The following steps can be used in order to determine the total cost to operate Lee's TV for a month of 30 days:

Step 1 - The arithmetic operations can be used in order to determine the total cost to operate Lee's TV for a month of 30 days.

Step 2 - According to the given data, Lee watches TV for 2 hours per day. So, the total consumption of electricity in one day is 500 watts.

Step 3 - So, the total consumption of electricity in 30 days is 15000 watts.

Step 4 - According to the given data, 1 kilowatt cost 10 cents. So, let the cost of the 15 kilowatts be 'x'.

Step 5 - So, the value of 'x' can be calculated as:

So, the total cost to operate Lee's TV for a month of 30 days is 150 cents.

Step-by-step explanation:

Lets us first calculate energy consumed by TV in 30 days.

Energy consumed by TV in one hour : 250 watts.

TV operated 2 hours a day

so energy consumer by TV in a day = 250 * 2 watts = 500 watts hour

Energy consumed by TV in 30 day = energy consumer by TV in a day * 30

         = 500*30 watts = 15,000 watt-hour

Convert total energy consumed in kilo watt hour  

we know that one kilowatt hour = 1000 watt-hour

Thus, 15,000 watt-hour = 15,000/1000 kilowatt-hour = 15 kilowatt-hour

cost of electricity = 10 cents per   kilowatt-hour

cost of electricity for 15 kilowatt-hour = 15* cost of electricity for one  kilowatt-hour( which is 10 cents)

=>15*10 = 150 cents

As $1 = 100 cents

hence 150 cents = $150/100 = $1.5 .

Thus, it cost $1.5 to to operate for a month of 30 days.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
