Answer:
23%
Step-by-step explanation:
if 100% of it = $680 then multiply 100 and the sale price then divide it with actual price to find what's % is 523.60
100 × 523.60 ÷ 680 = 77
if 523.60 is 77% then the discount amount is 23%

Answer:
n = 25/2, or n = 12 1/2
Step-by-step explanation:
It's essential that you use parentheses here to show how your numerals are grouped. I have made some assumptions here, and believe you meant:
(1 1/2)(n - 4 1/2) = 12.
First, convert 1 1/2 and 4 1/2 into improper fractions:
(3/2)(n - 9/2) = 12
Multiplying both sides by (2/3) eliminates the fractional coefficient (3/2):
n - 9/2 = (2/3)(12), or n - 9/2 = 8.
Again, eliminate the fraction by multiplying all terms by 2:
2n - 9 = 16
Then 2n = 25, and n = 25/2, or n = 12 1/2
Answer: 112 pieces
Step-by-step explanation:
1. Rewrite 
as a decimal. Divide the numerator and the denominator of the fractional part and add it to the integer part:
2. You know that each metal rod is 15 inches long. Then, you must divide the lenght of each one by 3.6:
3. The waste is 0.16, therefore, you obtain 4 pieces from a metal rod. The total pieces obtained from 28 metal rods are:
