Question

A pair of shoes that originally cost $79 are on sale for 35% off. Does the expression 0.65(.79) represent the sale price of the shoes (in dollars)? explain your reasoning

Answer 1

0.65(79) represents the correct sales price of the shoes (in dollars).

Explanation:

As per question, discount offered on cost price = 35% and

Cost Price = 79$

Calculating discount :

Discount on cost price =
`35\% * 79`

`\Rightarrow (35)/(100) * 79`

Now, it is know that we have to subtract the discount from cost price to get Sale Price:

`\text{Sale price = Cost price - Discount on cost price}`
`\Rightarrow \text{Discounted price = } 79 - (35)/(100) * 79\\\text{Taking 79 common}\\\Rightarrow 79(1-0.35)\\\Rightarrow .65(79)`

Hence 0.65(79) represents the correct sale price of the shoes in dollars.
