To find an increase in a line graph, look for an increasing slope.
The day that showed an increase in the number of burgers sold compared to the previous day is Friday (Fri).

Number of burgers sold on Wednesday and Thursday
= 27 + 17
= 44
Total sales on Wednesday and Thursday
= 44 x 4
= $176
Answer(s): (a) Fri; (b) $176
