A $500 television is on sale for 20% off. However, you must pay 6% in sales tax. What is the final price of the television after

GrogVix [38]

20% off means you are paying 80% of the original price ( 100% - 20% = 80%)

Multiply the price of the tv by 80% to find the sale price:

500 x 0.80 = 400

Now multiply the sales price by 1 plus the tax rate to find final cost:

400 x 1.06 = 424

Final price including tax is $424

Anit [1.1K]

Answer:

The correct option is D.

Step-by-step explanation:

Let x denote the years.

The information provided is:

The population of Metro City is 7420.
The population is decreasing by 152 people per year.
The population of Smallville is consistently 1200 less than half of Metro City.

From the provided data derive the equation for the population of Smallville x years after as follows:

$Y = [\frac{1}{2}\cdot (7420-152x)]-1200$

The population of Smallville is 2282 after x years.

Compute the value of x as follows:

$2282= [\frac{1}{2}\cdot (7420-152x)]-1200$

$\frac{7420-152x}{2}=2282+1200\\\\7420-152x=3482\times 2\\\\152x=7420-6964\\\\152x=456\\\\x=3$

Thus, the time it will take for Smallville's population to reach 2282 is 3 years.

The correct option is D.
