Answer:

First find what the sale price of the CD is. 30% off means the CD is selling for 70% of the original cost ( 100%-30% = 70%)

Multiply the original cost by 70%:

17.00 x 0.70 = $11.90 ( sale price)

Now you need to multiply the sale price by the tax percentage to find the amount of tax:

11.90 x 0.08 = 0.95 ( tax)

Now add the sale price and the tax for the total cost:

11.90 + 0.95 = $12.85

How Can associative Property be used to mentally find 48+82?

Marizza181 [45]

Associative property of addition represents this equation:
a + b = b + a
So, how would it be helpful with this given equation?
=> 48 + 82
=> Let's start with the ones place value.
(2 + 8) = 10, bring down 0, carry 1 then ( 4 + 8) = 12 + 1 = 13
So the answer is 130.
If we are going to do it vice versa, still expect that the same answer will occur.
