aleksandrvk [35]

Answer:

y\leq15.5

Step-by-step explanation:

The Total Amount taken to the store by Jerome = $20

He buys a book worth $4.50

Let y be the most he could spend on CDs

Since he is spending on books and CDs, the amount spent cannot be more than total sum he has, therefore:

y+$4.50\leq20

This is because he could spend either less than $20 or exactly $20

y\leq20-4.50

y\leq15.5 is the inequality to find the most he could spend on CDs.
