A store sells a package of 12 trading cards for $5.52. Use pencil and paper. Explain how you can tell that the unit price per card is less than $1. What is the unit price per card?

The cost of 12 trading cards are less than $12 so we can say that unit price of the card is lesser than $1.

Unit price per card is $0.46.

Step-by-step explanation:

Given:

Cost of 1 package of trading card = $5.52

Number of trading card in a package = 12

We need to explain how can we tell that the unit price per card is less than $1.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
