Step-by-step explanation:

Answer 2

The loss percent is 30%

Given : Jennifer sold a comic at 70% of the price at which she purchased it.

To find : The loss percent.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the loss percent)

Let, the purchasing price = x

So,

Selling price :

= x × 70%

= x × (70/100)

= 7x/10

Loss amount :

= Purchasing price - Selling price

= x - (7x/10)

= (10x-7x)/10

= 3x/10

Loss percent :

= 100 × (loss amount ÷ purchasing price)

= 100 × [(3x/10) ÷ x]

= 100 × [(3x/10) × (1/x)]

= 100 × (3/10)

= 30%

(This will be considered as the final result.)

Hence, the loss percent is 30%
