The correct answer and explanation is:

The correct answer is b. 8.525.

Here’s the explanation:

To add 3.625 and 4.9, follow these steps:

1. Align the numbers by the decimal point. This makes it easier to add. 3.625

• 4.900

2. Start adding from the rightmost column.
   • First, add the thousandths place: 5 + 0 = 5.
   • Next, the hundredths place: 2 + 0 = 2.
   • Then, the tenths place: 6 + 9 = 15. Write down 5 and carry over the 1 to the next column.
   • Finally, add the whole numbers: 3 + 4 = 7, plus the carryover 1, gives 8.
3. The result is 8.525.

The other options are incorrect because:

• a. 7.525 is too small.
• c. 41.15 is a completely incorrect value.
• d. 52.63 is much too large.

So, after adding the numbers correctly, the sum is 8.525.
