I'll give you a question, please answer with step-by-step reasoning process.
Frank's laundry detergent is double concentrated and will wash 80 loads of laundry. His detergent is usually $25.00 a bottle but they're having a sale. If he buys 2 bottles, both bottles will drop to $20.00 a bottle. How much does he spend, in cents, per load of laundry, if he buys 2 bottles of detergent?

25
If he buys 2 bottles, the price drops to $20.

00 per bottle so they cost 2 * 20 = $40.

00.

He can get 80 loads of laundry per bottle and he bought 2 bottles so that's 80 * 2 = 160 loads of laundry.

The detergent cost $40.

00 and he will be able to wash 160 loads of laundry so each load costs 40 / 160 = $0.

25.

Thus, the answer is 25
