Question

Amina sees a discount of 5% on a laptop. She can calculate the amount she has to pay for the laptop using the expression where b is the price of the laptop before the discount. If the price after discount is $494, which number from the set {500, 505, 510, 520, 525} is the value of b? A. $500 B. $505 C. $510 D. $520 E. $525

Answer 1

Answer:

D. $520

Step-by-step explanation:

Discounted price = $494

Discount in %=5%

Let the MRP be x

Then, MRP =

$x - \frac{x \times 5}{100} = 494 \\ x - \frac{x}{20} = 494 \\ \frac{20x - x}{20} = 494 \\ \frac{19x}{20} = 494 \\ x = \frac{494 \times 20}{19} = 520$

Therefore, the MRP of the laptop = $520
