Answer:
B
Step-by-step explanation:
The equation
represents the total number of kittens, where
represents <u>the number of weeks that have passed since Samantha started counting.</u>
This means options C and D are false, because they say <u>the total number of kittens that have come into the shelter</u>.
represents the number of weeks, weeks can be counted 0 weeks, first week, second week and so on, so option B is true (the domain is all whole numbers) because 0, 1, 2, 3, ... are whole numbers.
Number of weeks can't be a negative number. Since "real numbers" include negatives, therefore, we exclude option A.
Answer:
Rita must work 50 days to save at least $25.
Step-by-step explanation:
The amount Rita earns per hour = $10
The saving percentage = 5%
So, the savings of Rita per hour = 5% of $10
⇒5% of $10 = 
or Rita saves $0.5 per hour.
The amount she wants to save at minimum = $25
So, let she works at the minimum of k Days.
⇒
or, 
The number of hours she has to work = 50 days
Hence, Rita must work 50 days to save at least $25.
Answer:
The answer is "Principal of marginal analysis".
Step-by-step explanation:
To determine unless the benefits of even an aggressive resource would outweigh its costs, and therefore increase utility, individuals and businesses can use a valuation model to compare the risks versus the benefits of more activities, like whether to create or consuming more. It's the amount during which net value is greater than or equal to marginal cost that's the optimal quantity in this situation. The amount where the marginal social cost curve and consumer surplus line connect.
