- What is the interest rate that a bank offers if your principal money of ₱30,500.00 yields ₱4,575.00 interest after three years?
[tex]\tt\color{maroon}{===========================================}[/tex]
[tex]\large\underline{\rm\color {black}{ANSWER}:}[/tex]
- [tex]\large\underline\color{yellowgreen} {{\tt{I \: ≈ \: 5\%}}}[/tex]
[tex]\tt\color{maroon}{===========================================}[/tex]
[tex]\sf\underline\color {black}{FORMULA:}[/tex]
- [tex]\small\underline\bold\color {white}{I \: = \: P.R.T}[/tex]
[tex]\tt\color{maroon}{===========================================}[/tex]
[tex]\large\underline{\rm\color {black}{SOLUTION}:}[/tex]
- [tex]\small\underline\bold\color {white}{I \: = \:( \: 4575.00) \: (30500.00) \: (3)}[/tex]
- [tex]\small\underline\bold\color {white}{I \: = \:4575.00 \: \div \: 91500}[/tex]
- [tex]\small\underline\bold\color {white}{I \: = \:0.05 \: \times \: 100}[/tex]
- [tex]\small\underline\bold\color {white}{I \: = \:5\%}[/tex]
Hence, the interest rate after 3 years is 5%.
