Answer 3

Let's break down the expression step by step:

(8.4 • 0.55 + 3.28) • 9.2 - 43.78

Step 1: Evaluate the expression within parentheses: 8.4 • 0.55 + 3.28 = 4.62 + 3.28 = 7.9

Step 2: Multiply the result by 9.2: 7.9 • 9.2 = 72.68

Step 3: Subtract 43.78 from the previous result: 72.68 - 43.78 = 28.9

Therefore, (8.4 • 0.55 + 3.28) • 9.2 - 43.78 equals 28.9.
