Step-by-step explanation:
the equation is
x + 0.25 = 15.75
by subtracting 0.25 from both sides we get
x = 15.75 - 0.25 = 15.50
so, her hourly wage before the raise was $15.50.
she got a raise less than $1/ hour, so her new hourly wage should be less than $15.50 + $1 = $16.50. her new hourly wage of $15.75 is less than $16.50, so the answer is reasonable.
