Let x represent the price of a suit: If the suit is on sale at a discount rate of 30%, express the price of the suit at the discount rate in terms of x.
My Work:
Let x = price of suit before the discount rate.
Let P = price of suit at a discount rate in terms of x.
P = x(0.30)
Is this correct?
NO.
Skeeter supplied the correct one.
The key word.If the suit is on sale at a discount rate
That means that the seller will take off or deduct some money from the asking price.
When you shop, if you see and item tagged for sale at $10, but there is an announcement that the store will discount 10% if you buy now.
How much would you expect to pay?
10% of $10 is one dollar. So you would expect to pay $9 for the item.
[Price of Suit AFTER Discount] = [Price of Suit] MINUS ([Price of Suit] x 0.30)
