Question

Use I = PRT to solve.

(time is in years).
P = $400 find I
R = 9%
T = 0.25 years
(Remember 9% = .09 in decimal form)

Answer 1

Explanation:

Given,

`P = $400 find I\\R = 9%\\\\T = 0.25 years`

`T=0.25`(Remember 9% = .09 in decimal form)

So We convert it into a decimal form

`(9)/(100) =0.09`

Now we find the Interest,

`I=PRT\\`
`I = 400X0.09X0.25\\I=36X0.25\\I=9$`

9$ is the answer
