2. Solving Inequalities

3. Rules for Solving Inequalities
The goal of an inequality is to get the variable by itself
Use same rules as equations
1 exception
If dividing or multiplying by a negative number you must switch the inequality
AND: Graph Answer

4. Story Problems with Inequalities
Debbie has at most $60 to spend on clothes. She wants to buy a pair of jeans for $22 and spend the rest on t-shirts. Each t-shirt cost $8.
What don’t you know? Represent it with a variable! What do you know?
Is there more than 1 possible solution?
What type of inequality sign is needed?
22 + 8x ≤ $60

5. Practice
Brett has a $30 online gift voucher. He plans to buy as many books as he can. The cost of each book is $4.25 There is also a single shipping charge of $2.50 How many books can he afford without spending more than his gift voucher amount?
