Answer:

n=4 because we have a quarterly rate
After replace the values given we got:

If we round this answer to the nearest number we got approximately $598 after 5 years.
Step-by-step explanation:
For this case we can ue the compund interest formula for the future value given by:

Where P represent the initial amount , t the number of years and r the rate of interest on fraction. The value of n represent the number of times that the interest rate is compound in a year
For our case we have:

n=4 because we have a quarterly rate
After replace the values given we got:

If we round this answer to the nearest number we got approximately $598 after 5 years.
Answer:
constants
Step-by-step explanation:
Constants are the terms in the algebraic expression that contain only numbers. That is, they're the terms without variables. We call them constants because their value never changes, since there are no variables in the term that can change its value.
Answer:
The first one $1.42
Step-by-step explanation:
1.42x5=7.1 (cost of all envelopes)
12-7.1=4.9
4.9/14=0.35 (one postcard)
10 postcards= 3.5
1.42x15=21.3 (cost of all envelopes)
3.5+21.3=$24.80
Answer:
-1
i do not remember how to solve this but i just answered a question that had this problem in it on my algebra test and that is the right answer
