Question

In calibrating your sprayer after spraying 1/8 acre, you poured 4 1/8 gallons of water back to refill your 100 gallon tank. How many gallons of spray solution are you spraying?

a. 24 GPA
b. 31 GPA
c. 33 GPA
d. 43 GPA

Answer 1

The sprayer is using 33 gallons per acre (GPA) of spray solution when it used 4 1/8 gallons to spray 1/8 acre.

Step-by-step explanation:

To calculate the gallons per acre (GPA) that you are spraying with your sprayer, you need to determine the volume of solution used over a specific area. Given that you sprayed 1/8 acre and had to refill 4 1/8 gallons into your 100 gallon tank, we can set up the following equation:

v = volume used = 4 1/8 gallons = 33/8 gallons

a = area sprayed = 1/8 acre

GPA = gallons per acre = (v / a)

Thus, GPA = (33/8 gallons) / (1/8 acre) = 33 gallons per 1 acre.

Therefore, the amount of spray solution you are using is 33 gallons per acre (GPA).
