Define a variable and write an inequality. Then solve. A local summer basecall team plays 20 games each season. So far, they have won 9 games and lost 2. How many more games much they win this season to win at least 75% of all their games?
i know that they need to win 6 or more games but i don't know how to write an inequality to solve for the answer that i got. And my variable would be G = the number of future games that must be won
.75(20)-9 > or = 6 ?
75% of 20 games = 15 games
So they have to win AT LEAST 15 games.
Seeing as they have won 9 already, they need to win 6 more at least.
Hence the variable would be how many more wins would occur and the inequality is as you have written. (the term 'at least' refers to the mathematical symbol of greater than or equal to)
9 + G >= (0.75)x20 = 15
G >= 6
