Question

The weekly sales of burgers in a restaurant are given below. Find the difference between the highest and the least sales.

• A. 1,500
• B. 2,500
• C. 3,000
• D. 3,500

Answer 1

The correct option is B 2,500


As the y-axis is given in hundreds, we must multiply the values by 100.

From the graph, we observe:
Sale of burgers on Day 1 = 1,000
Sale of burgers on Day 2 = 2,000
Sale of burgers on Day 3 = 3,000
Sale of burgers on Day 4 = 1,500
Sale of burgers on Day 5 = 3,500
Sale of burgers on Day 6 = 2,000
Sale of burgers on Day 7 = 1,500



So, the least sales made is 1,000, and the highest sales made is 3,500.

Therefore, the difference between the highest and the least sales = 3,500 – 1,000 = 2,500
