last week's profit = $65 (positive)
This week's profit = -$25 (negative)
Part A
To write a subtraction expression to represent the current profit we simply subtract this week's amount of negative profit, to last week's profit:
• Subtraction expression: 62-25
For the addition expression, we simply add the negative value :
• Addition expression: 62+(-25)
