Perimeter = 2 × π × r
Perimeter = 2 × 3.14 × 9
Perimeter = 56.52
Perimeter = 56.52 ÷ 2
Perimeter = 28.26
The perimeter of a semicircle with a radius of 9mm is 28.26
Answer: Choice B
If you lower your rates by 6% you will increase the number of occupancies by 12%
========================================================
Explanation:
Price Elasticity of Demand is found by dividing the percent change of demand over the percent change in price

If the price drops 6% leads to a 12% increase in demand, then we get this elasticity

The absolute value of that result is 2. We work backwards going from 2 to see the relationship between the 12% and 6%.

Side notes:
- Choice A is incorrect as a price elasticity of demand larger than 2 means we have elastic (rather than inelastic) demand.
- Choice C is incorrect because while raising rates does bring in more money in certain situations, there's a limit to how much the price goes up before people stop showing up. The prices can't go up forever. Also, the fact we have an elastic product means people are either forgoing this hotel or finding a substitute.
- Choice D is incorrect. Products with high demand elasticity usually have substitutes. Any slight change in the price leads people to seek cheaper options. Unless we're dealing with a small town there are usually multiple hotels to choose from.
Multiply by the conjugate for the numerator
The item us going to cost 4.975
just convert the percent to decimal by moving the decimal point two spaces to the left and multiply it times the price and it will give you the discount the subtract the discount from original price and the result will be the new price.
99.50x.95=94.525
99.50- 94.55=4.975
you can round it up to 4.97
