The correct Answer is:
To solve the expression \( (21 + 99) \times (30 - 19.02) \), we will follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). ### Step-by-Step Solution: 1. **Calculate the first bracket: \( 21 + 99 \)** \[ 21 + 99 = 120 \] 2. **Calculate the second bracket: \( 30 - 19.02 \)** \[ 30 - 19.02 = 10.98 \] 3. **Multiply the results of the two brackets:** \[ 120 \times 10.98 \] 4. **Perform the multiplication:** \[ 120 \times 10.98 = 1317.6 \] Thus, the final answer is \( 1317.6 \).
