To Find:
Percentage of increase in the number of car washed=?
Solution:
we know that
Percentage Increase=Final Value−Starting Value|Starting Value x 100

Substituting the values,
percentage of increase in the cars =[tex]\frac{70-40}{40}\times100[/tex]
percentage of increase in the cars =[tex]\frac{30}{40}\times100[/tex]
percentage of increase in the cars =[tex]0.75\times100[/tex]
percentage of increase in the cars =75
