The correct Answer is:
To simplify the expression \(7\%\) of \(4000 - 12\%\) of \(550\), we can follow these steps: ### Step 1: Convert percentages to fractions We start by converting the percentages into fractions: \[ 7\% = \frac{7}{100} \quad \text{and} \quad 12\% = \frac{12}{100} \] ### Step 2: Calculate \(7\%\) of \(4000\) Now, we calculate \(7\%\) of \(4000\): \[ 7\% \text{ of } 4000 = \frac{7}{100} \times 4000 \] Calculating this gives: \[ = \frac{7 \times 4000}{100} = \frac{28000}{100} = 280 \] ### Step 3: Calculate \(12\%\) of \(550\) Next, we calculate \(12\%\) of \(550\): \[ 12\% \text{ of } 550 = \frac{12}{100} \times 550 \] Calculating this gives: \[ = \frac{12 \times 550}{100} = \frac{6600}{100} = 66 \] ### Step 4: Subtract the two results Now we subtract the result of \(12\%\) of \(550\) from \(7\%\) of \(4000\): \[ 280 - 66 = 214 \] ### Final Answer Thus, the simplified result is: \[ \boxed{214} \] ---
