Answer 1

To find out how much Mary had before she bought the computer, you can add the price of the computer to the amount of money she has left after the purchase.

The price of the computer is $299, and the amount Mary has left is $21.56.

So, we calculate:

\[
\text{Amount before buying the computer} = \text{Price of computer} + \text{Amount left}
\]

\[
= 299 + 21.56 = 320.56
\]

Thus, Mary had **$320.56** before she bought the computer.
