Question

the amount of water an electric dishwasher uses to wash dishes varies directly with the number of loads of dishes. the dishwasher uses 32 gallons of water to wash 4 loads of dishes. how many gallons of water will the dishwasher use to wash 10 loads of dishes?

Explanation:

Step1: Find water - per - load rate

First, find out how many gallons of water are used per load. Divide the total gallons of water by the number of loads. The formula is $\text{Water per load}=\frac{\text{Total water}}{\text{Number of loads}}$. Given that 32 gallons of water are used for 4 loads, so $\text{Water per load}=\frac{32}{4}=8$ gallons per load.

Step2: Calculate water for 10 loads

Then, to find the amount of water for 10 loads, multiply the water - per - load rate by the number of loads. The formula is $\text{Total water for 10 loads}=\text{Water per load}\times10$. Substitute the value of water per load (8 gallons per load) into the formula, we get $\text{Total water for 10 loads}=8\times10 = 80$ gallons.

Answer:

80
