Before discarding, carolee has 4 green cards, 3 red cards, 3 orange cards, and 1 gold card. if she discards the gold. are, what percent of her remaining cards are red?

Well 1st, the total of the cards (including gold) is 11. Then without the gold it is 10. So you take the number of red and the total and the fraction would be 3/10. and 3/10ths is 0.30 as a decimal, so to convert from a decimal to a percentage you move the decimal 2 spots to the right, therefore your answer is 30%

An equation would be Y=8/3x+10
