chad roth took out a $9,100 simple interest loan at 10% for 36 months. after 27 payments, the balance is $2,526.85. he pays off the loan when the next payment is due.
a.) what is the current month's interest?
b.) what is the final payment?

a) Current Interest is $75.8

b) the final payment will be $11,830

Step-by-step explanation:

Principal Amount = $9,100

Interest rate = 10% or 0.1

Time = 36 months = 3 yeras

Balance after 27 payments = $2,526.85

a) What is the CURRENT month's interest?

The formula to find interest is:

Interest = P*r*t

P= Principal

r = Interest rate

t = time in years

Interest = 9100*0.1*3

Total Interest = 2730

As total period is 36 months so, divide total interest by 36

Current Month Interest = 2730/36

Current Month Interest = 75.8

So, current month interest is $75.8

b) What is the final payment?

The formula used will be

A = P(1+r*t)

A = Final amount

r = interest rate

t = time

Putting values:

A = P(1+r*t)

A = 9100*(1+0.1*3)

A = 9100*(1.3)

A = 11,830

So, the final payment will be $11,830

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}
