The bar graph shows the number of dresses sold at Riordan's shop.
- In September, Riordan sold ______ times as many dresses as in December.
- Each dress was sold for $40. How much did he earn for the month when he sold the least number of dresses?
(a)
Number of dresses that Riordan sold in September = 90
Number of dresses that Riordan sold in December = 30
90 ÷ 30 = 3
In September, Riordan sold 3 times as many dresses as in December.
