ANSWER
B. x=3,y=2
EXPLANATION
The given equations are
and
We add the two equations to eliminate y.
This implies that that:
Simplify:
Divide both sides by 2.
We put x=3 into any of the equations to find y.
Let us substitute x=3 into equation (1) to get:
Divide both sides by -3 to get;
The solution is therefore x=,y=2.
See explanations on compound interest formula.
Step-by-step explanation:
Given that the formula which models the situation is;
This can be written as the compound interest formula where;
where
A=amount after the time period
P=starting amount=$300
r=interest rate=15%=0.15
n=number of compounding per year
t=time period
A.
P=$300, r=0.15, n=12
P(1+r/n)^nt
300(1+0.15/12)^12t
300(1.0125)^12t
A=300(1.0125)^12t
Introducing logs both sides
B.
Applying the compound interest formula where P=$300, t=4, n=4 and r=0.15
Interest= 544.61-300 =$244.61
C.
Finding the numeric expression to evaluate a yearly compounding interest rate you use n=1
D.
Given that P=$300, r=0.15, n=1,t=4 then, finding the amount and the interest will be;
interest to pay = 524.70-300=$224.70
