Three consecutive odd integers are such that the sum of the first and second is equal to 31 less than 3 times the third. find the integers.

x + x + 2 = 3(x + 4) - 31

Combine like terms

2x + 2 = 3(x + 4) - 31

Distributive property.

2x + 2 = 3x + 12 - 31

Combine like terms.

2x + 2 = 3x - 19

Subtract 2x from both sides.

2 = x - 19

Add 19 to both sides.

21 = x

The value of the first number is 21.

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)
