John wants to buy a dvd player. the price is $100, and the sales tax is 5%. store a is offering a 10% discount and store b is offering a $10 rebate. what would johns total cost be at the two stores?

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

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"
