The graph shows the number of burgers sold by a cafe in a week.
- Which day showed a decrease in the number of burgers sold compared to the previous day? Give your answer in this format. (Eg Mon)
- Each burger was sold at $10 each. How much money did the cafe earn from the total sales on Monday and Tuesday?
(a)
To find a decrease in a line graph, look for a decreasing slope.
The day that showed a decrease in the number of burgers sold compared to the previous day is Wednesday (Wed).
(b)
Number of burgers sold on Monday and Tuesday
= 18 + 32
= 50
Total sales on Monday and Tuesday
= 50 x 10
= $500
Answer(s): (a) Wed; (b) $500
