To find the percent of each type of card in the box, we first need to calculate the total number of cards:
\[ \text{Total cards} = \text{Birthday cards} + \text{Get-Well cards} + \text{Thank-You cards} \] \[ \text{Total cards} = 20 + 15 + 15 = 50 \]
Next, we calculate the percentage of each type of card using the formula:
\[ \text{Percentage} = \left(\frac{\text{Number of specific type of card}}{\text{Total number of cards}}\right) \times 100 \]
-
Birthday cards: \[ \text{Percentage of Birthday cards} = \left(\frac{20}{50}\right) \times 100 = 40% \]
-
Get-Well cards: \[ \text{Percentage of Get-Well cards} = \left(\frac{15}{50}\right) \times 100 = 30% \]
-
Thank-You cards: \[ \text{Percentage of Thank-You cards} = \left(\frac{15}{50}\right) \times 100 = 30% \]
Thus, the percentages of each type of card are:
- Birthday cards: 40%
- Get-Well cards: 30%
- Thank-You cards: 30%
