So, we know this:
<span> 5x+10y = 800
and we also know that the number of larger vehicles was 50.
So we can substitute:
</span>
<span>5x+10y = 800
</span>
<span>5x+10*50 = 800
and calculate:
</span><span>5x+500 = 800
and now subtract 500 from both sides:
5x=300
and divide by 5:
x=60.
and this is our answer: there were 60 smaller vehicles washed!

The slope of the linear equation is 15, so the correct option is B.
<h3>
How to get the slope of the line?</h3>
A linear equation can be written as:
y = a*x + b
Where a is the slope and b is the intercept.
For a line that passes through the points (x₁, y₁) and (x₂, y₂), the slope can be written as:
Here we have the two points (0.2, 3) and (0.4, 6), so the slope is:
So the slope of the line is 15, which means that the correct option is B.
