A Radio Was Bought For P510 At 15% Discount. What Was The Marked Price?

A radio was bought for P510 at 15% discount. What was the marked price?

Marked price - discount = Cost Price.

Marked price - 15% of Marked price = Cost price.

Let Marked price be x.

$x - \text{(15\% of x)} = 510$

$x - \Big(\dfrac{15}{100}\times{x}\Big) = 510$

$\dfrac{100x}{100} - \Big(\dfrac{15x}{100}\Big) = 510$

$\Big(\dfrac{100x-15x}{100}\Big) = 510$

$\Big(\dfrac{85x}{100}\Big) = 510$

$x = 510\times\dfrac{100}{85}=600$

Php 600 is the marked price.
