Question

A box of greeting cards contains 20 birthday cards, 15 get-well cards, and 15 thank-you cards.

Find the percent of each type of card in the box.


Birthday cards:
Get-Well cards:
Thank-You cards:

Answer 1

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:

\[
\text{Percentage} = \left(\frac{\text{Number of specific type of card}}{\text{Total number of cards}}\right) \times 100
\]

1. **Birthday cards**:
\[
\text{Percentage of Birthday cards} = \left(\frac{20}{50}\right) \times 100 = 40\%
\]

2. **Get-Well cards**:
\[
\text{Percentage of Get-Well cards} = \left(\frac{15}{50}\right) \times 100 = 30\%
\]

3. **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%
