Options

A. a. 220.3
B. b. 224.5
C. c. 190.3
D. d. 150

Answer

To evaluate \( 28\% \) of \( 400 \) plus \( 45\% \) of \( 250 \), we can follow these steps:

### Step 1: Convert percentages to fractions
We start by converting the percentages into fractions:
- \( 28\% \) can be written as \( \frac{28}{100} \)
- \( 45\% \) can be written as \( \frac{45}{100} \)

### Step 2: Calculate \( 28\% \) of \( 400 \)
Now, we calculate \( 28\% \) of \( 400 \):
\[ 28\% \text{ of } 400 = \frac{28}{100} \times 400 \]
Simplifying this:
\[ = \frac{28 \times 400}{100} = \frac{11200}{100} = 112 \]

### Step 3: Calculate \( 45\% \) of \( 250 \)
Next, we calculate \( 45\% \) of \( 250 \):
\[ 45\% \text{ of } 250 = \frac{45}{100} \times 250 \]
Simplifying this:
\[ = \frac{45 \times 250}{100} = \frac{11250}{100} = 112.5 \]

### Step 4: Add the two results
Now, we add the two results together:
\[ 112 + 112.5 = 224.5 \]

### Final Answer
Thus, the final answer is:
\[ \boxed{224.5} \]
