Agardener buys two kinds of fertilizer. fertilizer a contains 60% filler materials by weight and fertilizer b contains 40% filler materials by weight. together, the fertilizers bought by the gardener contain a total of 240 pounds of filler materials. which equation models this relationship, where x is the number of pounds of fertilizer a and y is the number of pounds of fertilizer b?
a) 0.4x + 0.6y = 240
b) 0.6x + 0.4y = 240
c) 40x + 60y = 240
d) 60x + 40y = 240

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

because they could drop even lower..
