You buy a flight to California for $305.72. The tax is 7.65%. What is the final cost of the ticket?



Show work and use method

Answers

Answer:309.83

Step-by-step explanation:

The final cost of the flight ticket $329.10758.

Given that, the cost of flight ticket is $305.72 and tax=7.65%.

What is the tax?

Taxes are mandatory contributions levied on individuals or corporations by a government entity—whether local, regional, or national. Tax revenues finance government activities, including public works and services such as roads and schools, or programs such as Social Security and Medicare.

Now, tax = 7.65% of 305.72

= 7.65/100 × 305.72

=0.0765 × 305.72

=$23.38758

Total cost = 305.72+23.38758

=$329.10758

Therefore, the final cost of the flight ticket $329.10758.

Okay, if the jeans were originally $80, take 40% off of that (40% of 80 is 32) so you’d get 48. Now take 48 and multiply by 1.07 (to get 107% of the $48, to find a percentage you can move the decimal place left 2 digits and multiply), so Justin would pay $51.36 in total.
