Question
A mixture of 7 pounds of fertilizer A, 21 pounds of fertilizer B, and 8 pounds of fertilizer C provides the optimal nutrients for a plant. Commercial brand X contains equal parts of fertilizer B and fertilizer C. Commercial brand Y contains one part of fertilizer A and two parts of fertilizer B. Commercial brand Z contain two parts of fertilizer A, five parts of fertilizer B, and two parts of fertilizer C. How much of each fertilizer brand is needed to obtain the desired mixture? Brand X = 12 lb Brand Y = 9 lb Brand Z = 9 lb Brand X = 12 lb Brand Y = 9 lb Brand Z = 15 lb Brand X = 9 lb Brand Y = 15 lb Brand Z = 12 lb Brand X = 12 lb Brand Y = 15 lb %3D Brand Z = 9 lb Brand X = 12 lb Brand Y = 15 lb Brand Z = 15 lb
