Subtract 5x from each side

8x-5x+6 < 5x-5x+21

3x+6 < 21

Subtract 6 from each side

3x+6-6<21-6

Your parents purchase a computer for $1,257.00 plus 6% sales tax. They decide to finance it through the store’s 0% program for 6
Katena32 [7]

Answer:

$111.59

Step-by-step explanation:

The total amount of the purchase was the cost of the computer plus the sales tax:

$1,257*1,06= $1,332.42

Now, to determine the interest that they will have to pay, you have to consider that the interest rate is 16,75% APR that is the annual percentage rate but as only 6 month have passed, the interest rate at this point that they have to pay is 8.375%:

$1,332.42*8.375%= $111.59

The interest that they will be charged is  $111.59

Students found that a box with sides 4cm, 4cm, and 5 cm held 192 Skittles.
Tpy6a [65]

Answer:

Volume is 80 cc

Ratio is 23 skittles per 20 cubic centimeter

Volume of a skittle is .416 cubic centimeters per skittle

Step-by-step explanation:

Volume = l*w*h = 4*4*5 = 80 cubic centimeters

192 skittles / 80 cubic centimeters is the ratio. You have to simplify it though.

192/80=46/40                  23 skittles per 20 cubic centimeters

The volume of a skittle is 80 cubic centimeters/192 skittles = .416 cm^3/skittle
