Question

Mark sold x pens for $2 each. He received less than $80 from the sale. Find the greatest possible number of pens he sold

Answer 1

Answer : 39

The answer would be 39 because he received less that 80 so subtract 2 from 80 (since each pen is $2) and you would get 78. Then you would divide 78 by 2, and that would be your answer.

Answer 2

$80-$2= $78 is the number less than $80, since the pens cost $2

78/2= 39 pens is the greatest number of pens sold

hope this helps
