The price without any of the discounts, the price would be $120

At store a it would be $108

At store b it would be $110

Step-by-step explanation:

For store a, we need to find 10% of $120. 10% of 100 is $20, so then we know that 10% of 120 will be more than $20. 100 in a decimal is 1.00, 120 is 1.2, so then the discount is 12 dollars. Now we need to subtract the discount from 120. 120-12=108.

At store b, we need to subtract $10 from 120. Since we don't have to calculate anything on this, we can simply subtract the $10. 120-10=110
