- Each bag was sold at the same price. How much was each bag sold for if a total of $780 was collected from the sale of all vests?
(a)
To find the greatest increase in sales, look for the steepest increasing slope.
Between Oct and Nov, the increase in the sales of the number of vests is the greatest.
(b)
Total number of vests sold from July to December
= 20 + 16 + 12 + 16 + 40 + 52
= 156
(c)
Amount that each vest was sold for
= 780 ÷ 156
= $5
Answer(s): (a) Oct and Nov; (b) 156; (c) $5
