The 
symbol means intersection, so everything that is in both sets, and the 
symbol means union, so the two sets combined.
So the answer is A.
So the answer is A.
Assume the average cost of maintaining a dog is the same from month to month. After 55 months, the dog had cost you a total of $
1 answer:
Answer:
Originally, you will <em>pay</em> $95.75 for the dog.
Step-by-step explanation:
Given:
Maintenance cost of dog after 55 months = $5,468.50
Maintenance cost of dog after 82 months = $8,053.75
To Find:
How much did you pay for the dog originally = ?
Solution:
It is stated that the maintenance cost is same from month to month
Now 82 - 55 = 27 months
For 27 we have paid
$8,053.75 - $5,468.50
$2585.25
But one month the amount paid will be

Answer:
The population will be 896 turtles 6 years later ⇒ B
Step-by-step explanation:
The exponential increasing formula is y = a, where
- y is the new value
- a is the initial value
- r is the rate of increase in decimal
- x is the time in years
∵ There are 300 turtles
∴ a = 300
∵ The population of the turtles exponentially increases 20% each year
∴ r = 20%
→ Divide it by 100 to change it to decimal
∵ 20% = 20 ÷ 100 = 0.2
∴ r = 0.2
∵ The time is 6 years
∴ x = 6
→ Substitute these values in the exponential formula above
∵ y = 300
∴ y = 300
∴ y = 895.7952
→ Round it to the nearest whole number
∴ y = 896
∴ The population will be 896 turtles 6 years later
