Answer 2

21 kWh

Explanation:

1. Subtract 25% from the original amount.

25% of 28 kWh is ...

0.25 × 28 kWh = 7.00 kWh

Subtracting this from 28 kWh, we find the usage after reduction to be ...

28 kWh - 7 kWh = 21 kWh

__

2. We know that if we reduce 100% of a quantity by 25%, then the resulting amount is (100 -25)% = 75% of the original. As a fraction, this is 75/100 = 3/4 of the original amount. Then the reduced usage is ...

(3/4) × (28 kWh) = 3·(7·4)/4 kWh = 3·7 kWh = 21 kWh

__

Mario must reduce his usage to 21 kWh or less.
