Step-by-step explanation:

$\frac{48}{2x + 7} = \frac{40}{5x - 2} \\ 48(5x - 2) = 40(2x + 7) \\ 240x - 96 = 80x + 280 \\ 240x - 80x = 96 + 280 \\ 160x = 376 \\ \frac{160x}{160} = \frac{376}{160} \\ x = 2.35$

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)
