During a rain shower, Jeanette collects 42 1 2 gallons of water in a rain barrel outside her home. She uses 1 1 4 gallons to water plants inside her house. Then, she uses 1 2 of the remaining water to wash a load of dirty laundry. How many gallons of water does Jeanette use to wash her laundry?

492 gallons

Step-by-step explanation:

Total gallons of water collected = 4212

Gallons used for watering of plants = 114

Remaining gallons = 4212 - 114

                               = 4098

She uses 12% of the remaining water to was her laundry.

So that, gallons of water used to wash her laundry = 12% of 4098

                                                                                     = × 4098

                                                                     = 491.76

                                                                     ≅ 492

She uses 492 gallons to wash her laundry.
