The income tax policy for residents of a tiny island nation that uses U. S. Dollars as its currency is as follows: The first $20,000 of a citizen’s income is taxed at a rate of 10%. The next $30,000 of the citizen’s income is taxed at a rate of 18%. Any amount over $50,000 is taxed at a rate of 27%.

How much income tax would an individual with an income of x dollars be charged, where x is at least $50,000?

0.10(20,000) + 0.18(30,000) + 0.27x
0.10(x − 20,000) + 0.18(x − 30,000) + 0.27x
0.10(20,000) + 0.18(30,000) + 0.27(x − 50,000)
0.10(20,000) + 0.18(30,000) + 0.27(50,000 − x)

C.

0.10(20,000) + 0.18(30,000) + 0.27(x − 50,000)

Step-by-step explanation:

Let's take this one step at a time. First, the $20000 dollars is taxed by 10% = .10 as a decimal. So the first term is

.10(20000)

Next, we have to add on the second term, wherein the next $30000 is taxed by .18. So the second term is

.10(20000) + .18(30000)

Then, we have to take whatever's left, whatever we haven't yet taxed, and tax it at a 27% rate. This means x-50000, not x, because we're taking whatever's over the initial 50000 that we've already taxed.

0.10(20,000) + 0.18(30,000) + 0.27(x − 50,000)

i would have to say it is c.

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
