Answer:
Inequality=19.76+x≥25; $5.24
Explanation:
To get free shipping, the total must be 25 dollars or more, causing us to use the symbol ≥. Then, it would be the price of the book plus x, whatever more we could add onto the purchase, to be greater than or equal to $25. This leaves us with the equation “19.76+x≥25”. Now, to solve this, we have to subtract 19.76 from both sides. 25-19.76=5.24. This means that you need to spend $5.24 more to be eligible for free shipping.
