Jennifer noticed that there were only 16 cars in theschool parking lot when she left school on Monday night.When she returned Tuesday morning there were 56 carsin the same parking lot. What is the percent of increase inthe number of cars in the parking lot?

Answer 1

we have that

16 cars represent the 100%

so

Applying proportion find out how much percentage represents the difference (56-16)=40 cars

100/16=x/40

solve for x

x=(100/16)*40

x=250%
