The graph shows the number of waffles sold by a cafe in a week.
- Which day showed a decrease in the number of waffles sold compared to the previous day? Give your answer in this format. (Eg Mon)
- Each waffle was sold at $2 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 waffles sold compared to the previous day is Wednesday (Wed).
(b)
Number of waffles sold on Monday and Tuesday
= 13 + 18
= 31
Total sales on Monday and Tuesday
= 31 x 2
= $62
Answer(s): (a) Wed; (b) $62
