When one group controls an industry or market by being the only provider, this is called MONOPOLY.
Mono - Greek monos means one or single
Poly - Greek polein means to sell.
Monopoly is a market where only one sells a certain good or service. In this type of market there is no competition thus the monopolist is not driven to improve his commodity because consumers have no other choice but to buy his product.
Answer:
increase in cost of living of 9.09%
Explanation:
The cost of living for 2016 is goven as
(10 pizzas*$10) + (7 jeans * $40)+ (20 gallons of milk * $3)
= 100 + 280 + 60= $440
The cost of living from 2017 is
(10 pizzas*$14) + (7 jeans * $40)+ (20 gallons of milk * $3)
= 140 + 280 + 60
= $480
The percentage increase in cost of living between 2016 and 2017= (Cost of living in 2017/cost of living in 2016)* 100
= {480/440}* 100
= 109.09%
So there was a increase in cost of living of 9.09%
Answer and Explanation:
The computation of composite score for each location is shown below:-
Composite score for A is
= 0.15 × 89 + .20 × 75 + 0.18 × 92 + 0.27 × 92 + 0.10 × 93 + 0.10 × 90
= 88.05
Composite score for B is
= 0.15 × 78 + .20 × 93 + 0.18 × 90 + 0.27 × 93 + 0.10 × 97 + 0.10 × 96
= 90.91
Composite score for C is
= 0.15 × 84 + .20 × 98 + 0.18 × 87 + 0.27 × 82 + 0.10 × 84 + 0.10 × 95
= 87.90
Therefore for computing the composite score for each location we simply multiply weight with A location and in the same manner of A, B and C
b. The maximum composite score from A, B and C is B
Answer:
1. 10s
2. Slower than normal
Explanation:
1. To calculate the normal time, we first take the average of Charlene's observed times:
Average of Charlene's observed time = 
= 8.5s
Her normal time is therefore: 
= 
= 10s
2. Since no of Charlene's observed time is higher than normal time of 10s, we can therefore conclude that her work perfomance should be rated as slower than normal.
