Answer:
52.09
Step-by-step explanation:
Follow the acronym PEMDAS (Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction) for order of operations problems.
1. Solve what is in parentheses. (9 - 7) = 2
48 ÷ 23 + 25 (9 - 7) = 48 ÷ 23 + 25 × 2
2. Divide. 48 ÷ 23 = 2.09
2.09 + 25 × 2
3. Multiply. 25 × 2 = 50
2.09 + 50
4. Add. 2.09 + 50 = 52.0
I know that 52.09 wasn't one of the options listed, but it is the exact answer. If you must choose one of those options, choose 50, since it is the closest.
