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

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
