Answer: We need to support her work for at least 15 days.

Explanation:

Juana's mother receives a daily payment of 30 soles .

She has already 120 soles.

Let x = Number of days to save at least 550 soles.

Then, Total she has after x days = 120+30x

According to the question, we have


120+30x \geq 550\\\\\Rightarrow\ 30x\geq550-120\\\\\Rightarrow\ 30x\geq430\\\\\Rightarrow\ x\geq(430)/(30)\\\\\Rightarrow\ x\geq14.33

i.e. minimum value for x=15

Hence, we need to support her work for at least 15 days.
