Manuela works at least 22 hours in a week.
Step-by-step explanation:
Given,
Per hour salary of Manuela = $15
Amount deducted = $125
Amount received = $205
Let,
x be the number of hours per week.
Per hour salary * Number of weeks - Amount deducted ≥ Amount received
[tex]15x-125\geq 205\\15x\geq 205+125\\15x\geq 330[/tex]
Dividing both sides by 15
[tex]\frac{15x}{15}\geq \frac{330}{15}\\x\geq 22[/tex]
Manuela works at least 22 hours in a week.
