- Each bag was sold at the same price. How much was each bag sold for if a total of $1800 was collected from the sale of all windbreakers?
(a)
To find the greatest increase in sales, look for the steepest increasing slope.
Between May and Jun, the increase in the sales of the number of windbreakers is the greatest.
(b)
Total number of windbreakers sold from January to June
= 36 + 24 + 16 + 24 + 36 + 64
= 200
(c)
Amount that each windbreaker was sold for
= 1800 ÷ 200
= $9
