The graph shows the number of pratas sold by a food outlet in a week.
- Which day showed an increase in the number of pratas sold compared to the previous day? Give your answer in this format. (Eg Mon)
- Each pratum was sold at $6 each. How much money did the food outlet earn from the total sales on Tuesday and Wednesday?
(a)
To find an increase in a line graph, look for an increasing slope.
The day that showed an increase in the number of pratas sold compared to the previous day is Saturday (Sat).
(b)
Number of pratas sold on Tuesday and Wednesday
= 24 + 18
= 42
Total sales on Tuesday and Wednesday
= 42 x 6
= $252
Answer(s): (a) Sat; (b) $252
