Inequality representing the situation is $\frac{1}{15}(60-s)\geq 3$ i.e. $s\leq 15$ .

Step-by-step explanation:

Let the number of days = s

Since, she has to work for 60 days and skipped for s days.

The number of days she worked = 60 - s

As, she worked at a rate of $\frac{1}{15}$ part of a blanket.

So, she worked at $\frac{1}{15}(60-s)$ days in total.

Since, she has to make minimum of 3 blankets, we get the inequality,

$\frac{1}{15}(60-s)\geq 3$

i.e. $(60-s)\geq 3\times 15$

i.e. $(60-s)\geq 45$

i.e. $-s\geq 45-60$

i.e. $-s\geq -15$

i.e. $s\leq 15$

So, she can skip the days less than 15 and still meet her goal.

Hence, the inequality representing the situation is $\frac{1}{15}(60-s)\geq 3$ i.e. $s\leq 15$ .

The solution plotted is given below.
