Marked price $700 discount $210 what is the rate of discount and sales price

The rate of discount can be calculated by dividing the discount amount by the marked price. In this case, the discount amount is $210 and the marked price is $700.

Rate of Discount = (Discount Amount / Marked Price) x 100
= ($210 / $700) x 100
= 0.3 x 100
= 30%

The sales price can be calculated by subtracting the discount amount from the marked price.

Sales Price = Marked Price - Discount Amount
= $700 - $210
= $490

Therefore, the rate of discount is 30% and the sales price is $490.
