Part 1:

The table showing the decreasing debt is shown as follows:

\begin{tabular}
{|c|c|c|c|}
Starting Balance&Interest Accrued&Payment&Closing Balance\\[1ex]
\$1,853.42&\$22.39&\$400&\$1,475.81\\\$1,475.81&\$17.83&\$400&\$1,093.64\\\$1,093.64&\$13.21&\$200&\$906.85\\\$906.85&\$10.96&\$200&\$717.81\\\$717.81&\$8.67&\$200&\$526.48\\\$526.48&\$6.36&\$200&\$332.84\\\$332.84&\$4.02&\$200&\$136.86\\\$136.86&\$1.65&\$138.51&-
\end{tabular}

The column for interest accrued is obtained by the folmular

I=P(1+0.155)^{\frac{1}{12}}

where P is the month's starting balance.



Part 2:

From the table, the last payment is $138.51



Part 3:

The total amount paid by the time the credit card is payed of is the summation of the "payment" column of the table.

Thus, the total amount is given by:

Payment\ total=2(400)+5(200)+138.51=\$1,938.51



Part 4:

The debt ratio is given by

Debt\ ratio= \frac{debt}{limit} = \frac{1,853.42}{3,000} \approx0.62

Rashid [163]

Any linear function is of the form y=mx+b

Here m is slope and b is y intercept.

Slope is difference in y divided by different in x values .

In the question for 5 persons cost is $100 and for 10 persons cost is $162.50

So the points are (5,100) and (10,162.50)

Slope m=\frac{162.50-100}{10-5}=12.50

We can find the value of b by taking m=12.50 and (x,y)=(5,100)

Substitute these values in y=mx+b

100=12.50(5)+b

100=62.50+b

Subtracting 62.50 both sides

b=100-62.50

b=37.5

a) Put m=12.50 and b=37.50 to get the equation

y=12.50x+37.50

b)Rate of change is the m value or the slope of the function.

Initial value that is (5,100) gives us one of the points to find the rate of change.
