• A. 50%
• B. 45%
• C. 57%
• D. 60%

Answer 1

Answer:

C. 57%

The approximate percentage increase in the number of eraser boxes sold from 2018 to 2020 is 57% (or 57.14%).

Step 1: Find the sales values from the bar graph

• Eraser boxes sold in 2018 = 35 (thousand)

• Eraser boxes sold in 2020 = 55 (thousand)

---

Step 2: Find the increase in sales

• Increase = 55 − 35 = 20 (thousand)

---

Step 3: Calculate the percentage increase

• Percentage Increase = (Increase / Sales in 2018) × 100

• Percentage Increase = (20 / 35) × 100

• Simplify 20 / 35 by dividing both by 5 = 4 / 7

• (4 / 7) × 100 = 400 / 7 = 57.14% (or approximately 57%)
