The bar graph shows the number of skirts sold at Bobby's shop.
- In July, Bobby sold ______ times as many skirts as in September.
- Each pair of skirts was sold for $40. How much did he earn for the month when he sold the most number of skirts?
(a)
Number of skirts that Bobby sold in July = 20
Number of skirts that Bobby sold in September = 10
20 ÷ 10 = 2
In July, Bobby sold 2 times as many skirts as in September.
(b)
To find the most number of skirts sold in a month, look for the highest point in the line graph.
