Answer:
r = 9.86%
Explanation:
The formula for calculating the future value of an invested amount yielding a compound interest is given by:
where:
FV = future value = $16,000
PV = present value = $10,000
r = interest rate = ?
n = number of compounding period per year = 1
t = time in years = 5
∴ 
dividing both sides by 10,000
to remove the power of 5, we have to take the 5th root of both sides:
Using your calculator:
1.09856 = 1 + r
∴ r = 1.09856 - 1 = 0.09856
r = 0.0986 = 9.86%
∴ r = 9.86%
Answer:
by calculating the elasticity of demand.
Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.
Price elasticity of demand = percentage change in quantity demanded / percentage change in price
If the absolute value of price elasticity is greater than one, it means demand is elastic. Elastic demand means that quantity demanded is sensitive to price changes.
Demand is inelastic if a small change in price has little or no effect on quantity demanded. The absolute value of elasticity would be less than one
Demand is unit elastic if a small change in price has an equal and proportionate effect on quantity demanded.

Answer:
$8058
Explanation:
10/20/5 stands for a series of discount rates applicable on the list price. It means on total amount, 10% discount is allowed, then post deduction of this 10%, a further 20% on the balance is allowed and then a further 5% is allowed on the balance.
In the given case, single equivalent discount would be calculated as follows,
$25,500 × 10% = $2550
Then, ($25,500 - 2550) × 20%= $4590
Then, ($25,500 - 2550 - 4590) × 5% = $918
Single equivalent discount amount = $2550 + 4590 + 918 = $8058
