How much money is in Joe's savings account after 3 years if he deposited $400 at the beginning of the year and the account pays 4% annual simple interest?

$448

Step-by-step explanation:

To calculate Joe's savings, we can use the formula for simple interest:

P = Po*(1+r*t)

Where P is the final value, Po is the inicial value, r is the interest and t is the time in years.

So, In our problem, we have that Po = 400, r = 4% and t = 3, then we can find P:

P = 400*(1+0.04*3)

P = 400*1.12 = $448

Joe has $448 in his savings.

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
