The graph shows the number of pratas sold by a coffee shop 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 $4 each. How much money did the coffee shop earn from the total sales on Wednesday and Thursday?
(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 Friday (Fri).
(b)
Number of pratas sold on Wednesday and Thursday
= 21 + 14
= 35
Total sales on Wednesday and Thursday
= 35 x 4
= $140
Answer(s): (a) Fri; (b) $140
