Melanie is going to a book sale. All the books are priced for $2 each, including sales tax. She can spend no more than $15. Which inequality represents the number of books Melanie can buy?

x ≤ 7

Step-by-step explanation:

Let the cost of each book be $2

Let the amount of book she can buy be x

If she can spend no more than $15

Amount of book she can buy≤ Total amount/cost of each book

Amount of book she can buy ≤ $15/$2

Amount of book she can buy ≤ 7.5

x ≤ 7.5 OR x ≤ 7

Hence the required inequality is x ≤ 7. Less than or equal to was used since she can't spend more than $15

x ≤ 7

hope this helps

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
