Eva is showing her work in simplifying (7.3 − 7.2) − 3.8 + 3.7. In which step did Eva make an error? Step 1: (7.3 − 7.2) − 3.8 + 3.7

Step 2: 7.3 + (−7.2 − 3.8) + 3.7 (commutative property)

Step 3: 7.3 − 11 + 3.7

Step 4: 7.3 + 3.7 − 11 (commutative property)

Step 5: 11 − 11 = 0

Step 2; she wrote commutative instead of distributive
Step 4; she wrote commutative instead of distributive
Step 4; she wrote commutative instead of associative
Step 2; she wrote commutative instead of associative
