Answer 2

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's solve the expression step-by-step:

1. Perform the division inside the parentheses first: 42.12 ÷ 0.3 = 140.4

2. Now, evaluate what's inside the parentheses: 42.12 ÷ 0.3 - 112.4 = 140.4 - 112.4 = 28

3. Next, perform the multiplication: 1.03 × 28 = 28.84

4. Finally, add the last term: 28.84 + 1.26 = 30.10

So, the solution to the expression is 30.10.
