Question

Principal: $4,000 at 6% for a) 4 years, b) 4 months, and c) 4 days.

Answer 1

If you're asking for the interest:

a) 960

b) 80

c)2.63 approx.

Explanation:

interest = principal x rate x time OR
`I = prt`

TIME IS IN YEARS.

Thus, the first would be
`I = 4000 *4 *6%`% = 960

Second: 4 months =
`(1)/(3)` year

I = 4000x
`(1)/(3)`x6% = 80

Third: t = 4 days =
`(4)/(365)`year

I = 4000x6%x
`(4)/(365)` ≈ 2.63
