Answer:
$11.34 Discounted Price Including Tax
Step-by-step explanation:
CD is $12.00
10 percent off of 12 dollars is:
12 x .10 = $1.2
12 - 1.2 = $10.8 WITHOUT TAX!!
5/100 = 0.05
0.05 x 10.8 = .54 (Tax itself)
10.8 (Discounted price) + .54 (Tax) = $11.34 Discounted Price Including Tax
We can simplify this equation and find the value of k.
k ÷ 2 + 1 - 1k = -2k
k ÷ 2 + 1 = -k
k + 1 = -2k
1 = -3k
k = -1/3
Answer: 20%.
Step-by-step explanation:
Given, The price of a shirt is marked down from $12.50 to $10.00.
Previous price = $12.50
New price = $10.00

Now, the percent decrease of the shirt = 

Hence, the percent decrease of the shirt = 20%.

Answer:
7 is the positive whole number which we can multiply by 3 and add 1, or multiply by 2 and add 8; and it will give the same answer.
Step-by-step explanation:
Multiplying the positive whole number 7 by 3 and adding 1 will get:
(7 × 3) + 1 = 21 + 1 = 22
Multiplying the positive whole number 7 by 2 and adding 8 will get:
(7 × 2) + 8 = 14 + 8 = 22
Therefore, 7 is the positive whole number which we can multiply by 3 and add 1, or multiply by 2 and add 8; and it will give the same answer.
