To find out how much money Mary had before she bought the computer, we need to add the amount she has left after the purchase to the cost of the computer.
Mary has $21.56 left and the computer cost $299.
So, we calculate:
\[
\text{Amount Mary had before purchase} = \text{Cost of the computer} + \text{Amount left}
\]
\[
\text{Amount Mary had before purchase} = 299 + 21.56 = 320.56
\]
Therefore, Mary had **$320.56** before she bought the computer.
Mary has $21.56 left and the computer cost $299.
So, we calculate:
\[
\text{Amount Mary had before purchase} = \text{Cost of the computer} + \text{Amount left}
\]
\[
\text{Amount Mary had before purchase} = 299 + 21.56 = 320.56
\]
Therefore, Mary had **$320.56** before she bought the computer.
