A town library recorded these monthly visits:
January: 1,200 February: 1,050 March: 1,400 April: 1,750
Which statement is supported by the data?
Show answer & explanation
Answer: A
Visits rose by 25% from March to April.: Correct. (1,750 − 1,400) ÷ 1,400 = 350 ÷ 1,400 = 0.25, or 25%.
Visits increased every month from January to April.: Visits fell from 1,200 in January to 1,050 in February.
April had twice as many visits as January had.: Twice January would be 2,400; April had 1,750.
Visits fell by 15% from January to February.: The drop was 150 ÷ 1,200 = 12.5%, not 15%.
Check each claim against the numbers; compute percent change as (new − old) ÷ old.
