To find out how much Mary had before she bought the smartphone, you can add the price of the smartphone to the amount of money she has left after the purchase.
Price of the smartphone: $78
Amount left after the purchase: $11.43
Now, add these two amounts together:
Amount Mary had before the purchase = Price of smartphone + Amount left
Amount Mary had before the purchase = $78 + $11.43
Amount Mary had before the purchase = $89.43
So, the correct answer is **$89.43**.
