Jason earns $35.50 on monday, spends $24.00 on tuesday, and earns $12.50 on wednesday. which equation shows how the associative property can be used when adding these rational numbers?

35.50 + (−24.00) + 12.50 = −24.00 + 35.50 + 12.50
[35.50 + (−24.00)] + 12.50 = 35.50 + [(−24.00) + 12.50]
35.50 + (-24.00) + 12.50 = 35.50 + 12.50 + (−24.00)
(35.50 + (−24.00)) + 12.50 = (−24.00 + 35.50) + 12.50
