To find an increase in a line graph, look for an increasing slope.
The day that showed an increase in the number of waffles sold compared to the previous day is Saturday (Sat).
(b)
Number of waffles sold on Tuesday and Wednesday
= 32 + 23
= 55
Total sales on Tuesday and Wednesday
= 55 x 4
= $220
Answer(s): (a) Sat; (b) $220
