Answer:

The correct answer is option B.

Step-by-step explanation:

The number of pounds of Fertilizer A = x

Percentage of fillers in Fertilizer A = 60%

Amount of fillers in of Fertilizer A= 0.6x

The number of pounds of Fertilizer B = y

Percentage of fillers in Fertilizer B = 40%

Amount of fillers in of Fertilizer B= 0.4y

Total amount of fillers bought by gardener = 240 pounds

Equation models this relationship: 0.6x + 0.4y = 240
