Tom bought a PS4 on Black Friday for 25% off. If the system sells for $399, what is the sales price of the PS4?

Delicious77 [7]

Answer:

The sales price of the PS4 is $532.

Step-by-step explanation:

The system sells for $399 after giving 25% off on a Black Friday on the sales price.

Let the sales price of the PS4 system is $x.

Then after giving 25% discount the price will become $x(1 - \frac{25}{100}) = 0.75x$

Therefore, 0.75x = 399

⇒ x = 532

Therefore, the sales price of the PS4 is $532. (Answer)

WILL GIVE 5 STARS TO THE PERSON WHO HELPS WITH AN EXPLANATION!!! If the 32 ounce bottle is 20% more than the typical bottle, how

Aleks04 [339]

So if 32 oz is 20% more than the average bottle, you multiply 32 by .20 which gives you 6.4. This means that the 32 oz bottle is 6.4 oz more than the regular bottle. Furthermore, 32 - 6.4 = 25.6 so that's how big the typical bottle is.

3/4+?/2=13/4 what is answer

Otrada [13]

The answer is x=5.

Solve for x. (The question mark should be x.)

$\frac{3}{4}+\frac{x}{2}=\frac{13}{4}\\\frac{3}{4}+\frac{x}{2}-\frac{3}{4}=\frac{13}{4}-\frac{3}{4}\\\frac{x}{2}=\frac{5}{2}\\\frac{2x}{2}=\frac{5\times 2}{2}\\x=5$
