Answer:
The amount of chamomile tea that has to be used in order to obtain a mixture that costs $14.32 per pound is 8.997 pounds
Step-by-step explanation:
In order to find out the amount of chamomile tea that must be used in the mixture to obtain a 14.32 $ per pound, we can use an weighted average where the price points for each kind of tea are the weights and "c" is the amount of chamomile that we have to use in order to obtain the price per pound that we want. So we have:
(18.5*c + 12.23*18)/(c + 18) = 14.32
18.5*c + 220.14 = 14.32*(c+18)
18.5*c + 220.14 = 14.32*c + 257.76
18.5*c - 14.32*c = 257.75 - 220.14
4.18*c = 37.61
c = 8.997 lb
The answer for the question below is C
Answer: x = 17 
Step-by-step explanation:
From the question: y α x
⇒ y = kx
y=4 and x = 10 implies
4 = 10k
k = 4/10
k = 2/5
substitute k = 2/5 into the equation
y = 2/5 x
When y = 7 , the equation becomes
7 = 
35 = 2x
35/2 =x
Therefore : 17
x =
Answer:
divide both side of inequality by 4 but don't flip the symbol
The answer would be (x+1) and (x+10) so E
