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)

Solve this r/6=5 2/3
myrzilka [38]
First, incorporate the 5 into the 2/3 fraction by multiplying the 5 by the 3 and then adding that quantity by the 2, which now makes the fraction:

Now set it up with the equation:
r/6 = 17/3
r/6×3 = 17/3×3
r/3 = 17
r/3×3 = 17×3
r = 51
