¿Cuál de las dos opciones le recomendarías al señor Alberto?

Mr. Alberto decides to buy a car in order to perform taxi services. The price of the vehicle is S/45 000, but only S/20 000 is available. He then decides to finance the missing money through a bank. If between the two loan plans offered, you must choose one:

Which of the two options would you recommend to Mr. Alberto?

we know that

The compound interest formula is equal to

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]

where

A is the total amount due

P is the amount owed

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

Plan I

[tex]t=2\ years\\ P=\$45,000-\$20,000=\$25,000\\ r=0.05\\n=1[/tex]

substitute in the formula

[tex]A=25,000(1+\frac{0.05}{1})^{1*2}[/tex]

[tex]A=25,000(1.05)^{2}[/tex]

[tex]A=\$27,562.50[/tex]

Plan II

[tex]t=3\ years\\P=\$45,000-\$20,000=\$25,000\\ r=0.03\\n=1[/tex]

[tex]A=25,000(1+\frac{0.03}{1})^{1*3}[/tex]

[tex]A=25,000(1.03)^{3}[/tex]

[tex]A=\$27,318.18[/tex]

Compare

Plan I ----> t=2 years A=$27,562.50

Plan II----> t=3 years A=$27,318.18

therefore

Plan II is more favorable because the total amount to pay is less and the time to pay is greater than Plan I.
