The bar graph shows the number of coats sold at Zane's shop.
- In September, Zane sold ______ times as many coats as in December.
- Each coat was sold for $80. How much did he earn for the month when he sold the least number of coats?
(a)
Number of coats that Zane sold in September = 120
Number of coats that Zane sold in December = 30
120 ÷ 30 = 4
In September, Zane sold 4 times as many coats as in December.
(b)
To find the least number of coats sold in a month, look for the lowest point in the line graph.
In November, Zane sold the least number of coats.
Number of coats that Zane sold in November = 10
Amount that Zane earned for the month when he sold the least number of coats
= 10 x 80
= $800
Answer(s): (a) 4; (b) $800
