Math HSAP Question of the Week.
Tubby Tires is offering a 25% discount on tires. How much can you save if you buy tires regulary priced at $225.00? What would be the new price of the tires after the discount?
Great job guys. Both of your answers are correct. If you are willing, I would like you to show some of the other students in class, how you solved the problem. Keep up the good work.
i changed my % to a decimal by moving it two places to the left. Then i Multiplied my decimal by the price of the tires. And then i subtracted the discount from the regular price to get the answer.
Quentin, you did an excellent job explaining how you got your answer. Kendrick (Mr. EA), if you have a percent and there is no decimal, the decimal starts to the far right of the number. Example 24% = 24.%, Then you move the decimal two places to the left and remove the percent sign. .24
If there is already a decimcal there you still move it two places to the left and fill in 0's as needed. Examples: 2.3% = .023 26.9% - .269 3% = .03 Try these: (change from percent to decimal) 14% = 9.7% = 34.9% = 5% = 49% = Good Luck!
Kenrick, those answers are all correct. We will continue to work with fractions ans decimals while preparing for HSAP. Let me know if we need to have more review with these.
