 12.90 cents

Step-by-step explanation:

well i took the tax off which is 50cents since its the CD's

.50+.50= $1..00

so 26.80-1.00 = 25.80

divide tht by 2 u get 12.9 the price of one CD

$12.90

Step-by-step explanation:

0.50*2=1 (taxes for both of them)

26.80 - 1=25.80(the tax being cut off)

25.80 divided by 2= 12.90(dividing the number without taxes with 2 getting the amount of the 2 cds without taxes)

Hope this helps and I am from your other question :)

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.
