The graph shows the number of pratas sold by a food outlet in a week.
- Which day showed a decrease in the number of pratas sold compared to the previous day? Give your answer in this format. (Eg Mon)
- Each pratum was sold at $7 each. How much money did the food outlet earn from the total sales on Saturday and Sunday?
(a)
To find a decrease in a line graph, look for a decreasing slope.
The day that showed a decrease in the number of pratas sold compared to the previous day is Thursday (Thu).
(b)
Number of pratas sold on Saturday and Sunday
= 26 + 35
= 61
Total sales on Saturday and Sunday
= 61 x 7
= $427
Answer(s): (a) Thu; (b) $427
