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 determine the total number of cards.

Total number of cards = Number of birthday cards + Number of get-well cards + Number of thank-you cards
Total number of cards = 20 + 15 + 15 = 50

Now we can calculate the percentage of each type of card.

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

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

3. **Thank-You cards:**
\[
\text{Percentage of thank-you cards} = \left( \frac{\text{Number of thank-you cards}}{\text{Total number of cards}} \right) \times 100
\]
\[
\text{Percentage of thank-you cards} = \left( \frac{15}{50} \right) \times 100 = 30\%
\]

In summary, the percentages are:
- **Birthday cards:** 40%
- **Get-Well cards:** 30%
- **Thank-You cards:** 30%
