We simply divide the money with the number of cards and we wiil get a price per card.

Also, we will transform 5.25 from decimal to a fraction, and in fractions, because is .25, we'll make it in quarters, this number is 5*4/4 + 1/4 = 21/4.

21/4/25/1 = 21/100 = 0.21$ per one trading card.

The cost of one trading card obtained using the principle of proportionality is $0.21

Given the Parameters :

25 trading cards = $5.25

Let the Cost of one trading card = b

We could set up a proportional system to calculate the Cost of one trading card as follows :

25 cards = $5.25

1 card = b

Cross multiply :

25b = $5.25

Divide both sides by 25 to isolate b

25b/25 = 5.25 / 25

b = $0.21

Therefore, one trading card costs $0.21
