Sue has 4 pieces of wood. the lengths of the wood are 1/3 feet,2/5 feet,3/10 feet and 1/4 feet. which piece of wood is the shortest?

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)

8+(1)(8)

8+8

16

retail price is $16.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
