No Jeremy can not find the cost of the sneakers by adding the percents, you have to the math one sale discount at a time.
The answer is $45.90.
Step-by-step explanation:
You have to multiply $60 by 15%, getting $9. Subtract 9 from 60 and get the first discount price: $51. Then you will multiply 51 by `10% and get 5.1, subtract 5.1 from 51 and get your final sale price $45.90. If you added the percents together you would get an incorrect value of $45. Close but not the correct answer.
