Find the solution to this differential equation:
db/dt+3b=60 b(1)=80 b=?

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13

$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
