First, we need to find the minimum score she needs to have a 12 point average. She has already played 6 games, and will play 1 more. 12 x 7 = 84 We need to add her point totals from the previous 6 games together, then subtract that total from the minimum score. 10+12+10+8+14+15 = 69 84-69 = 15 Kelly needs to earn 15 points on the 7th game to get an average score of 12 points per game.
Constants are those numerical values that will never change, despite the value of x. The easiest way to find them are by finding those numbers that are not affecting x in any way.
