A sprayer has a 320-gallon capacity tank. If it is calibrated to apply 16 gallons of solution per acre, how many acres will be sprayed with each fill?

Explanation:
This question tests how to convert a rate per acre into the total area covered by a full tank. If the sprayer holds 320 gallons and applies 16 gallons for each acre, divide the tank capacity by the per-acre rate: 320 ÷ 16 = 20. This works because 20 acres × 16 gallons per acre equals 320 gallons exactly. The other numbers would require more gallons than the tank holds (for example, 30 acres would need 480 gallons, 36 acres would need 576 gallons). So a full tank sprays 20 acres.
