Answer 1

To find out how much Mary had before she bought the smartphone, we need to add the price of the smartphone to the amount of money she has left.

The price of the smartphone is $78, and she has $11.43 left.

So, we calculate:

\[
\text{Amount before purchase} = \text{Amount left} + \text{Price of smartphone}
\]

\[
\text{Amount before purchase} = 11.43 + 78
\]

\[
\text{Amount before purchase} = 89.43
\]

Therefore, Mary had **$89.43** before she bought the smartphone.
