The piecewise function below models a portion of the tax brackets for a particular State. Let x be the amount of taxable income.
f(x) =
0.15x
Osxs 20,000
2,917.50 +0.20(x - 20,000) 20,000 < x < 50,000
8,917.50 +0.25(x - 50,000) 50,000 < x < 100,000
21,417.50 +0.30(X-100,000)
X > 100,000
Determine the tax for a person with taxable income of $82,450.

is there a question here?

step-by-step explanation:

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours

the answer is 8.64
