Answer:
9 birds
Explanation:
f is finches, h is herons, w is warblers, t is total
f+h+w=t
All but 6 means subtracted from the total
f=t-6
h=t-6
w=t-6
Adding the three equations gets 3t-18 and plug that back in and isolate
t=3t-18
t= 9
The price elasticities of demand of sugar-free gummy bears and of ordinary gummy bears is -0.8 and -2.3 respectively.
<h3>How to calculate price elasticity</h3>
Change in price of gummy bears = $2. 60 to $3
Elasticity of demand of sugar-free gummy bears =
[(273-379 / (273+379)/2] ÷ [(3.00-2.60)/(3.00+2.60) / 2]
= [-18/166] / [0.4/2.8]
= -0.10843373493975 / 0.14285714285714
= - 0.75903614457826
Approximately, -0.8
Elasticity of demand of regular gummy bears:
Sugar free = [(273-379) / (273+379)/2] ÷ (3.00 +2.60) / 2]
= [-106/326] / [0.4/2.8]
= -0.32515337423312 / 0.14285714285714
= -2.2760736196318
Approximately, -2.3

Answer:
You're wrong, the answer is C) 24
Explanation:
4d/h when b=3, d=12, h=2, r=7
Plug in the variables --> 4(12)/(2)
PEMDAS says do 4*12 first so --> 48/2
Which is 24.
