Drinks, x, and popcorn, y. 38.75 = 5x+2y 37.25 = 3x + 4y Let's solve this using the elimination method subtract the 2nd row from the first <span>7x=40.2<span>5 divide both sides by 7 to isolate x </span></span><span>x=5.7<span>5
Substitute x into an equation </span></span><span><span>10(5.75)+4y=77.5 multiply </span></span>57.5+4y=77.<span>5 subtract 57.5 from both sides </span>4y=77.5−57.<span>5 Simplify </span>4y=2<span>0 divide both sides by 4 to isolate y y = 5
To check you would plug x and y into the equations and see if it equals properly...
The price of drinks is $5.75, the price of popcorn is $5.
Do 80% of 25 which would be 20 and then you can determine how many they lost so if they won 20 games and they have 25 games total then they lost 5 games.
