I had the similar test and got it right so it should be B
Answer:
The estimate is less than the actual length of the CD.
Step-by-step explanation:
Consider the provided information.
Maurice's new CD has 12 songs. Each song lasts between 3 and 4 minutes.
That means the minimum length of the CD should be: 12×3=36 minutes.
The maximum length of the CD should be: 12×4=48 minutes
He estimates that the whole CD is about 30 minutes long.
30 minutes is less than 36 minutes.
That means, the estimate is less than the actual length of the CD.
Hence, the correct statement is: The estimate is less than the actual length of the CD.
Using the equation A=P(1+(r/n))^nt.
n=monthly, so it's 12.
t=19 years
r=6.9% as a decimal is .069
P=47,000
.069/12=.00575
.00575+1=1.00575
nt=12*19=228
1.00575^228=3.695
3.695*47000=$173,711
Answer: $173,711
