$2000 was borrowed for 4 years with an interest rate of 3% compounded annually. What is the total amount owed at the end of the

kompoz [17]

Answer:

$\$2,251.02$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the total amount owed

P is the amount of money borrowed

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=4\ years\\ P=\$2,000\\ r=3\%=3/100=0.03\\n=1$

substitute in the formula above

$A=2,000*(1+\frac{0.03}{1})^{1*4}$

$A=2,000*(1.03)^{4}$

$A=\$2,251.02$

Daniel pays $496 in advance on his account at the athletic club. Each time he uses the club, $12 is deducted from the account. W

rewona [7]

Answer:

$b = 496 - 12v$

The balance is $256

Step-by-step explanation:

Given

$Payment = \$496$

$Deduction = \$12$

Required

Determine the balance after 20 visits

Represent the balance with b

Represent the visitation with v

The relationship between the given parameters is:

$Payment = Deduction * Visitation + Balance$

This gives:

$496 = 12 * v + b$

$496 = 12v + b$

Make b the subject

$b = 496 - 12v$

To get the actual balance after 20 visitation;

Substitute 20 for v

$b = 496 - 12 * 20$

$b = 496 - 240$

$b = 256$

Hence:

<em>The balance is $256</em>
