Is this from k12? i am a k12 student, and the answer should be 2.2 units but I could be wrong.
Answer:
24 pounds of Rift Valley coffee
26 pounds of Mexican Shade Grown coffee
Step-by-step explanation:
If R is pounds of Rift Valley coffee, and M is pounds of Mexican Shade Grown coffee, then:
R + M = 50
12.10 R + 13.10 M = 12.62 (50)
Substitute:
12.10 R + 13.10 (50 − R) = 12.62 (50)
12.10 R + 655 − 13.10 R = 631
R = 24
M = 26
To get the answer, all you have to do is 715 ÷ 55 which equals 13 (hours)
Can’t see the coordinate plan so I can’t answer it
