22 complete cars and half of one car were washed on Sunday. Solution: Given that  Drama club held a car wash on Saturday and Sunday. Total car washed on Saturday and Sunday = 60  Lost [tex]40 \%[/tex] can on Sunday. Need to calculate number of car washed on Sunday. Let assume number of cars they washed on Saturday = x As they lost [tex]40\%[/tex] of cars on the Sunday Number of cars washed on Sunday = Car washed on Saturday – [tex]40\%[/tex] of car washed on Saturday[tex]\Rightarrow x-40 \% \text { of } x=\mathrm{x}-0.40 x=0.60 x[/tex]Total number of cars washed on Saturday and Sunday = Number of cars washed on Saturday + Number of cars washed on Sunday   [tex]\begin{array}{l}{\Rightarrow 60=x+0.60 x} \\\\ {\Rightarrow 60=1.6 x} \\\\ {\Rightarrow x=\frac{60}{1.6}=37.5}\end{array}[/tex]So car washed on Sunday = [tex]0.60 x=0.60 \times 37.5=22.5 \mathrm{ cars}[/tex]That is 22 complete cars and half of one car were washed on Sunday.
