Answer 1

To find out how much money Mary had before she bought the smartphone, we need to add the amount she has left ($11.43) to the price of the smartphone ($78).

So, the calculation would be:

\[
\text{Total amount before buying smartphone} = \text{Amount left} + \text{Price of smartphone}
\]
\[
= 11.43 + 78 = 89.43
\]

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