Answer:
b. 60
Step-by-step explanation:
We have been given a formula 
, where x represents the number of small vehicles and y represents the number of larger vehicles.
To find the number of small vehicles, we will substitute 
in the given equation as:
Therefore, 60 small vehicles were washed in total and option 'b' is the correct choice.
Height:shadow=2.5:3
2.5/3=6.7/x
cross multiply aka times both sides by 3x
2.5x=20.1
divide both sides by 2.5
x=8.04
answer is 8.04ft

The population of mastertown is 23,000 in 2012.
Assume that the increase of the population has a rate of 2% increase annually. Writing an equation model will help us find the number of population in the coming years. Here is the equation model using the geometric sequence formula.
An = A1 * r^(n-1)
Population = starting population 2012 * 0.02^[(year - 2012) - 1]
