Question

What is the interest on $4,000 at 3% for 4 years?
$4,800
$160
$480
$48

Answer 1

`\huge{ \fbox{ \sf{ \: \$ \: 480}}}`

Explanation:

`\star{ \sf{ \:Principal \: ( \: P \: ) = \$ \: 4000}}`

`\star{ \sf{ \: Rate \: ( \: R \: ) \: = 3\% = (3)/(100) = 0.03}}`

`\star{ \sf \: \: Time \: ( \: T \: ) \: = 4 \: years}`

`\underline{ \sf{Finding \: the \: Interest}}`

`\boxed{ \sf{Interest \: = P \: * \: R \: * \: T}}`

`\longmapsto{ \sf{ \: Interest = 4000 * 0.03 * 4}}`

`\longmapsto {\sf{Interest = \$ \: 480}}`

Hope I helped!

Best regards! :D
