Answer:

b. 60

Step-by-step explanation:

We have been given a formula 5x+10y=800, 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 y=50 in the given equation as:

5x+10(50)=800

5x+500=800

5x+500-500=800-500

5x=300

\frac{5x}{5}=\frac{300}{5}

x=60

Therefore, 60 small vehicles were washed in total and option 'b' is the correct choice.
