- Each waffle was sold at $6 each. How much money did the restaurant earn from the total sales on Saturday and Sunday?
(a)
To find a decrease in a line graph, look for a decreasing slope.
The day that showed a decrease in the number of waffles sold compared to the previous day is Thursday (Thu).
(b)
Number of waffles sold on Saturday and Sunday
= 42 + 50
= 92
Total sales on Saturday and Sunday
= 92 x 6
= $552
Answer(s): (a) Thu; (b) $552
