A word problem is a mathematical problem written as one sentence or more that requires application of mathematical knowledge to a 'real-life' scenario.
From the question,
Let m represents the money Gianna had
Gianna paid $4.75 for a strawberry smoothie.
we can calculate the money she had by subtracting the $4.75 paid for a strawberry smoothie from m and equating it to her the balance she has currently
This can be expressed mathematically as
m-4.75=12.34
By adding 4.75 to both sides of the equation, we have
m-4.75+4.75=12.34+4.75
m=$12.34+$4.75
m=$17.09
Hence, from the expression, Gianna had $17.09 before she bought strawberry smoothie
