Answer

The month of April had the greatest profit while the month of January had the greatest loss.

Work Step by Step

From Exercise 52, the profit or loss (a negative value means a loss) for each month is: \begin{array}{ccccccccc} &\text{January:} &-\$700 \\&\text{February:} &-\$100 \\&\text{March:} &\$700 \\&\text{April:} &\$900 \\&\text{May:} &\$0 \\&\text{June:} &\$700 \end{array} Thus, the month of April had the greatest profit while the month of January had the greatest loss.
