Stores often mark up items each year to cover inflation. last year, a cd at juan’s tunes cost $12.95. this year, the cost was marked up 8%. the store also gave anyone who bought four cds this year a 10% discount. explain the steps to find the final cost for the four cds this year.

12.95x8%=1.036

12.95+1.036=13.986

13.986x4=55.94-10%=

$50.3496

rouding up would be $50.35 for 4 cds this year

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
