With a sprayer having a 4-gallon tank and 20 gpa calibration, how many acres can you spray per full tank?

Explanation:
The key idea is how many acres you can treat given a specific gallons-per-acre rate. At 20 gallons per acre, covering one acre requires 20 gallons of spray. A 4-gallon tank can supply 4 gallons, so the area you can treat is 4 ÷ 20 = 0.2 acres. So, per full tank, you can spray about 0.2 acres (roughly one-fifth of an acre). If you needed to cover a full acre, you’d need five full tanks at this rate, or you’d need to adjust the tank size or the application rate.
