Katie Cole purchased a mountain bike with an installment loan that has an APR of 14%. The mountain bike sells for $762. The stor

Brums [2.3K]

Answer-

Finance charge is $99

Solution-

Price of mountain bike = $762

The store's financing requires a 15% down payment, so the present value of annuity will be,

$762-(762\times \frac{15}{100})=\$647.7$

We know that,

$\text{PV of annuity}=P[\frac{1-(1+r)^{-n}}{r}]$

$PV\ of\ annuity=647.7,\\\\P=?,\\\\r = 14\%\ annually=\frac{14}{12}\%\ monthly=\frac{14}{1200}\ monthly\\\\n=24\ months$

Putting the values,

$\Rightarrow 647.7=P[\dfrac{1-(1+\frac{14}{1200})^{-24}}{\frac{14}{1200}}]$

$\Rightarrow P=\dfrac{647.7}{\frac{1-(1+\frac{14}{1200})^{-24}}{\frac{14}{1200}}}$

$\Rightarrow P=\dfrac{647.7}{20.8277}$

$\Rightarrow P=\$31.10$

With a monthly payment of this, he will be paying in 24 months will be,

$=31.10\times 24=\$746.4$

Then,

$\Rightarrow \text{Total payment}=\text{Down payment+Monthly payment}=(762\times \frac{15}{100})+(746.4)=\$861$

The extra amount he will be paying,

$=861-762=\$99$

Evaluate the summation of 2 n plus 5, from n equals 1 to 12..

kirza4 [7]

Let f(n) = 2n + 5. Then we must simply calculate (f1), f(2), ..., (f12). And we have that f(1) = 2*1 + 5 <=> f(1) = 7; f(2) = 2*2 + 5 <=> f(2) = 9; f(3) = 2*3 + 5 <=> f(3) = 11. And so on. It's easy to see that the rest of the results will be 13, 15, 17, 19, 21 and so on. So the summation will be S = 7 + 9 + 11 +... + 29 <=> S = 216
