Alana makes and sells homemade bracelets. She made a profit of $65 last week. This week, she donated some bracelets to charity. Her profit at the end of this week can be represented by -$25. What is the DIFFERENCE between last week’s profit and this week’s profit?

$40 is the difference. One is positive(W1), one is negative(W2). Therefore, you subtract.

Step-by-step explanation:

You subtract week ones profit and week twos profit.

65 - 25 = $40

You subtract because she had a negative profit for week two and/or a profit below 0.
