Answer:
The easiest way to test if water is acidic is to use litmus paper. Litmus paper is a paper that contains special dyes that will change color when exposed to acids or bases. In your case, if you dip blue litmus paper into water samples and it turns pink or red, then the water is acidic.
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
