Answer:
1st problem: b) 
2nd problem: c) 
Step-by-step explanation:
1st problem:
The formula/equation you want to use is:
where
t=number of years
A=amount he will owe in t years
P=principal (initial amount)
r=rate
n=number of times the interest is compounded per year t.
We are given:
P=2500
r=12%=.12
n=12 (since there are 12 months in a year and the interest is being compounded per month)
Time to clean up the inside of the ( ).
----------------------------------------------------
2nd Problem:
Compounded continuously problems use base as e.
P is still the principal
r is still the rate
t is still the number of years
A is still the amount.
You are given:
P=2500
r=12%=.12
Let's plug that information in:
.
Answer:
3/4
Step-by-step explanation:
it's for sure 3/4!!!!!
Answer:
a: 3
b: 12
c: 15
Step-by-step explanation:
12 + 15 = 27
There are 27 total.
Since there are 27 in all, it's best if each small rectangle value is 3.
Answer: B.x(0.75)
Step-by-step explanation:
If the jacket has a cost of 
, but has 
off and we have to add the 
in tax, we can write all in the following expression:
Where:
is the cost
is the percent off
is the tax
Then:
This can be also rewritten as:
Hence, the correct option is B.
When you expand the equation, you will have
9x + 9=25 + x
Next you have to collect like terms
+x will go over the equality sign to become -x. The same applies to +9
9x - x=23 - 9
9x minus x is 8x
8x=14
Divide both sides by 8
x=14/8
You will have 1 6/8
6 is the remainder while 1 is the number of times 8 divided 14.
In decimal, it will be 1.75
Hope that helped. Good luck
