(A) 20
(B) 45
(C) 50
(D) 60
(E) 70



We can see that, in March, the LOWEST daily shirt sales was 20 and the GREATEST daily shirt sales was 70
So, the RANGE = 70 - 20
= 50

(D) 40%
(E) 70%


The solid bar denotes the AVERAGE daily shirts sales for that month.

In January, the average was about 25
In February, the average was about 35

Percent increase = 100(new - old)/old

So, percent increase = 100(35 - 25)/25
= 100(10)/25
= 40

D
