Question

While shopping online, Jenny orders a CD that costs $14 and a book that costs b dollars. If she spends at least $25 she gets free shipping. Write an inequality for this situation.

Answer 1

An inequality is like a “regular” equation but instead of using an equal sign, it uses an inequality sign like <, >, etc..

For this question, you may use:

14+b>25

See, 14+b is greater than or equal to 25 because the question says “at least” 25.
