Explanation Method: An increase in the quantity is denoted by a positive sign and a decrease in the quantity is denoted by a negative sign. Calculation: Consider that Jane’s bank balance was $300 on January 1. Checks for $45, $55, $165, $35, and $100 are written and deposits of $75, $25, and $400 are made. A check is represented by a negative integer and a deposit by a positive integer. So, write the checks amounts by prefixing the negative sign. So, the expression for Jane’s transactions is: 4 " To determine b) To find: The balance in Jane’s account at the end of the month.
