Jeremy cannot/ can find the cost by adding the percents.

.

25% off of $60 is equal to $45.00/35.00/25.00/45.90

.

15% off of $60, then subtracting 10% from that cost is equal to 35.00/25.00/38.25/45.90...

.

The two total costs are equal/not equal



can someone help me solve this question pls?

Answer 1

No, Jeremy can not find the cost of the sneakers by adding the percents, you have to math one sale discount at a time.

The answer is $45.90.

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 of $45.90. If you added the percents together you would get an incorrect value of $45. Close but not the correct answer.
