Calculate the state income tax owned on a 40,000 per year salary
kenny6666 [7]

Answer:

The state income tax to be paid will be $ 2,300.

Step-by-step explanation:

Given that an annual salary of $ 40,000 pays a state income tax of 5.75% of said value, to determine the total amount of tax to be paid, the following calculation must be made:

40,000 x 5.75 / 100 = X

230,000 / 100 = X

2,300 = X

Therefore, the state income tax to be paid will be $ 2,300.

QUICKK <br> Solve for x. You must write your answer in fully simplified form.
aalyn [17]

To solve divide both sides by 4 to cancel out the 4 on the x side to get x alone. Then just do -10/4. That gives you 2.5 so (X=2.5). Hope I helped and have a great day and night
