Question

Owen and Eva spent the same amount of money making copies. Owen spent 14 cents per copy, while Eva spent 10 cents per copy. What is the SMALLEST possible difference between the number of copies Eva made and the number of copies Owen made?

A) 1
B) 2
C) 3
D) 4

Answer 1

In this item, we are to determine the least common factor or multiple (LCM) of 14 and 10 in order to determine the amount of money that both have spent. The LCM of 14 and 10 is equal to 70. Thus, each spent 70 cents.

With this amount of money, Owen will have 5 copies and Eva will have 7 copies. Thus, the smallest possible difference between the number of copies is 2.
