You deposit 2000 in an account earning 3% interest compounded monthly.
1 answer:
Answer:
a. 3641.51
b. 1641.51
Step-by-step explanation:
The future value formula will tell you the amount in the account in 20 years.
<h3>Formula</h3>FV = P(1 +r/n)^(nt)
Principal P is compounded n times per year at annual rate r for t years.
<h3>Application</h3>The future value of the account with P=2000, r=0.03, n=12, and t=20 will be ...
FV = 2000(1 +0.03/12)^(12·20) = 2000(1.0025^240) ≈ 3641.50999
<h3>a.</h3>The account value in 20 years will be 3641.51.
<h3>b.</h3>The first 2000 of account value is the principal, so the interest is ...
interest = 3641.51 -2000
interest = 1641.51

You must travel at 42 mph for 4 hours
<em><u>Solution:</u></em>
Time varies inversely as rate of motion
Let "t" be the time required
Let "r" be the rate of motion
Then, we get
Where, "k" is the constant of proportionality
<em><u>You travel 3 hours at a rate of 56 mph</u></em>
Substitute t = 3 and r = 56 in eqn 1
<em><u>Find the rate you must travel for 4 hours</u></em>
r = ? and t = 4
Substitute t = 4 and k = 168 in eqn 1
Thus you must travel at 42 mph for 4 hours
