This is because the rectangle's area is 168ft. Then you can find the semicircle's area by finding the area of a circle with a radius of 6 and then dividing that by 2.
The equation we use here is:
x is for the number of games he played on first day, y is the games on second day. The coefficients are the decimal form of percentages.
Simplify:
To find x we need to use the ratio. We have 85/100 as the first day's ratio and because the games needs to be whole, we can simplify this as 17/20. So in first day, he played at least 20 games and won 17 of them.
When we plug the 20 into the equation as x:
So he needs to play at least 30 games in order to get his score to 94%.
