Answer :
Answer:
The correct option is D.
Step-by-step explanation:
It is given that Christopher took out a 4 year loan for $1150 at a sports-equipment store to be paid back with monthly payments at a 4.2% APR, compounded monthly.
The formula for amount after compound interest is
[tex]A=P(1+\frac{r}{n})^{t}[/tex]
Where, P is principal, r is rate of interest, n is number of time interest compounded in a period, number of periods.
According to the given information,
P=1150
r=0.042
n=12
t=9
Put these values in the above formula,
[tex]A=1150(1+\frac{0.042}{12})^{9}[/tex]
[tex]A=1186.73631355[/tex]
[tex]A\approx 1186.74[/tex]
Christopher owe $1186.74 when he begins making payments. Therefore the correct option is D.
