3. Alice took out a simple interest loan to purchase carpet for her house. The interest on the loan
was $1081.43. If the interest rate was 9.75% for 3 years, what was the price of the carpet?

Respuesta :

Answer:

The price of the carpet was [tex]\$3,697.20[/tex]

Step-by-step explanation:

we know that

The simple interest formula is equal to

[tex]I=P(rt)[/tex]

where

I is the Final Interest Value

P is the Price of the carpet

r is the rate of interest  

t is Number of Time Periods

in this problem we have

[tex]t=3\ years\\ P=\$?\\ I=\$1,081.43\\r=0.0975[/tex]

substitute in the formula above

[tex]1,081.43=P(0.0975*3)[/tex]

[tex]1,081.43=P(0.2925)[/tex]

Solve for P

[tex]P=1,081.43/(0.2925)[/tex]

[tex]P=\$3,697.20[/tex]
