Question

The given bar graph shows the number of items purchased by Amy at a stationery store.
If Stacy purchased 10 fewer pens and pencils and 15 more erasers and sharpeners than Amy, which of the following statements is correct?

• A. All of the above.
• B. Stacy purchased 100 erasers.
• C. Stacy purchased 95 sharpeners.
• D. Stacy purchased 55 pens and pencils in total.

Answer 1

The correct option is A All of the above.

Solution:
In the given bar graph, we can observe that:
Number of pens: 45
Number of pencils: 30
Number of erasers: 85
Number of sharpeners: 80

Given, Stacy purchased 10 fewer pens and pencils and 15 more erasers and sharpeners than Amy.
So, number of pens purchased by Stacy $=45-10=35$
Number of pencils purchased by Stacy $=30-10=20$
Number of erasers purchased by Stacy $=85+15=100$
Number of sharpeners purchased by Stacy $=80+15=95$

Therefore, total number of pens and pencils purchased by Stacy $=35+20=55$

All the given statements are correct.
