Can you please help me with this problem?

Question

Marietta was given a raise of 0.75 per hour, which gave her a new wage of $12.25 per hour. Write and solve an equation to determine Marietta's hourly wage before her raise. 

Answer 1

The new wage is equal to the old wage plus her raise, so:

x + 0.75 = 12.25
or
x= 12.25-0.75

Meaning x is her original wage, being $11.50
