Step-by-step explanation:
Sajia can sell 21 books she can sell if she comes back on sunday and the required inequality is 
<em><u>Solution:</u></em>
Given that Sajia has 30 Books in her library
She sold 9 books at the thrift store on Saturday
To find: We have to write and solve an inequality to determine number of more books she can sell if she comes back on sunday
Let "x" be the number of more books she can sell if she comes back on sunday
<em><u>We can write a inequality as:</u></em>


Now moving 9 from L.H.S to R.H.S we get,

On solving 30 - 9 = 21,

So Sajia can sell 21 books she can sell if she comes back on sunday
Answer: 5 weeks
Explanation:
Jess starts with $22 and saves $5 per week, Rosie has $10 and saves $8 per week.
In order to find an equal amount of money between the two girls is by finding a common denominator.
Jess- 22, 27, 32, 37, 42
Rosie- 10, 18, 26, 34, 42
Since we found that they can both end up with $42, after a certain amount of weeks have passed, now you’ll want to count how many numbers are in each row to find the amount of weeks it took to get to an equal amount
