Answer:

  3/250 gallons per square yard

Step-by-step explanation:

To find gallons per square yard, divide gallons by square yards.

Chantel used (3 tanks)×(3/4 gallon/tank) = (9/4 gallons).

Her backyard area is (12 1/2 yd)×(15 yd) = 187 1/2 yd².

The rate of application was ...

  (9/4 gallons)/(375/2 yd²) = 3/250 gallons/yd² = 0.012 gallons/yd²
