Answer:
2.4%
Step-by-step explanation:
Total amount of payments:
5 years * 12 months/year * $78.40/month =
= $4704.00
Amount of interest paid in 5 years:
$4704 - $4200 = $504
Amount of interest paid in 1 year:
$504/5 = $100.80
Annual percent rate of interest:
$100.80/$4200 * 100% = 2.4%
Answer: 2.4%
254 is your answer
b.
The given function is
Recall that the reciprocal of the cosine ratio is the secant ratio.
This implies that;
We take the inverse cosine of both sides to obtain;
25% = 1/4
1/4(40)
Divide 40 by 4 to remove the 1/4
10
25% of 40 is 10.
The answer is 19.10 $
