Question

The chart shows the power ratings of 3 clothes dryers and the time needed to dry a load of 10 towels.

power/time
x/4,370/25
y/4,420/22
z/4,150/26


What is the difference in energy used between the dryer that uses the greatest amount of energy and the dryer that uses the least amount?

Answer 1

.20 kWh

Step-by-step explanation:

its right on edge

Answer 2

12010

Step-by-step explanation:

Given:

power time

4,370 25

4,420 22

4,150 26

To find: difference in energy used between the dryer that uses the greatest amount of energy and the dryer that uses the least amount

Solution:

Energy = power × time

For clothes dryer x:

energy = 4370 × 25 = 109250

For clothes dryer y:

energy = 4420 × 22 = 97240

For clothes dryer z:

energy = 4150 × 26 = 107900

Dryer x uses the greatest amount of energy and dryer y uses the least amount of energy.

Difference in energy used between the dryer that uses the greatest amount of energy and the dryer that uses the least amount = 109250 - 97240 = 12010
