You want to buy some wallpaper to decorate your kitchen. A roll of wallpaper is on sale for $10. Write and solve an inequality to determine how many rolls of wallpaper you can buy and spend no more than $50.

Let x be the number of rolls of wallpaper that you can buy to decorate your kitchen. Since each roll costs $10, the total cost for x rolls is 10x. This value should be not be more than $50. The inequality that is best described by the condition is,

10x ≤ 50

Solving for x gives an answer of x ≤ 5.
