3. You can find 10% and multiply by the correct amount.  Ex: 40% off of $50.00  10% is $5.00.  $5.00 X 4 (for 40%) = $20.00  So 40% off of $50.00 is $20.00  How much would you have to pay?

4. 4.3 Activity When you save 40%, you pay 60%  40% of $50.00 is $20.00  So 60% of $50.00 is $30.00.

11. Finding the original price is the same as finding the whole. $22.40 is the part. What percent does $22.40 represent of the original price? $22.40 is 70% of what number? Why is 70% used instead of 30%? 30% off the original price is the same as paying 70% of the original price.

12. 4.3 Activity A store purchases an item for x dollars. The store needs to sell this item for more than x dollars (markup) to cover operating costs and to make a profit. A store purchases an item for $2 and sells it for $4. This represents a 100% markup ($2 + 100% of $2).

13. 4.3 Activity Reasoning: If a $10 item sells for $25, the $10 item was marked up 150% and the selling price is 250% of $10. (100% of $10) + (150% of $10) = (250% of $10) = $25
