Answer 1

No, Jeremy cannot find the cost of the sneakers by adding the percents. By finding 25% off of $60, then 15% off of $60, and subtracting 10% from the cost, the total cost of the sneakers can be calculated.

Step-by-step explanation:

No, Jeremy cannot find the cost of the sneakers by adding the percents. Adding the percents would result in an overestimate of the discount. Let's calculate the cost step-by-step:

1. Find 25% off of $60:
   $60 x 0.25 = $15
2. Find 15% off of $60:
   $60 x 0.15 = $9
3. Subtract 10% from the cost:
   $9 - ($9 x 0.10) = $9 - $0.90 = $8.10

So, the cost of the sneakers after applying the discounts is $8.10.
