To find a decrease in a line graph, look for a decreasing slope.
The day that showed a decrease in the number of burgers sold compared to the previous day is Thursday (Thu).
(b)
Number of burgers sold on Saturday and Sunday
= 33 + 38
= 71
Total sales on Saturday and Sunday
= 71 x 5
= $355
Answer(s): (a) Thu; (b) $355
