Answer:
20%
10%
0.5
5%
Step-by-step explanation:
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
Percentage change in price = (1.2/1) - 1 = 20%
Percentage change in quantity demanded = 450/500 - 1 = 10%
Answer:
0.12 = 12%
Step-by-step explanation:
To find this probability, we need to multiply the probability of getting route B, and the probability of getting home by 4 P.M if we choose route B.
If the probability of choosing route A is 60%, we have that the probability of choosing route B is 100% - 60% = 40%
Then, we have that the probability of getting home by 4 P.M. when choosing route B is 30%, so the final probability is:
P = 40% * 30% = 0.4 * 0.3 = 0.12 = 12%

Answer:
x=7 and y=4
Step-by-step explanation:
I will use the elimination method:
Since the co-efficient of both y's are the same number but different signs we add the 2 equations to eliminate the y:
3x + y =25
+ + +
2x - y = 10
Simplify:
5x=35
Divide both sides by 5:
5x÷5=35÷5
Simplify:
x=7
Substitute this into either equation 1 or 2 ( I chose 1):
3(7) + y = 25
21 + y = 25
Subtract 21 from both sides and simplify to get y:
21+y-21=25-21
y=4
Therefore x=7 and y=4
Answer:
Step-by-step explanation:
<u>Given</u>
- Investment P = $16800
- Interest rate r = 5% = 0.05
- Final amount A = $18900
- Time t = ?
<u>Use the formula</u>
- A = P(1 + rt), where A - final amount, P - investment, r- interest rate, t- time
<u>Substitute the given numbers and solve for t:</u>
- 18900 = 16800( 1 + 0.05t)
- 1 + 0.05t = 18900/16800
- 1 + 0.05t = 1.125
- 0,05t = 0.125
- t = 0.125/0.05
- t = 2.5 years
