$40
40*90/100 = 36
You just have to be careful with the rest of the problem
A) the man is 40 and the daughter is 8
b)in 8 years when the man is 48 and the daughter is 16
By rewriting the given line, we can see that the slope is equal to -1/2 or -0.5
<h3>
How to get the slope of the given line?</h3>
Remember that a line is:
y = a*x + b
Where a is the slope and b is the y-intercept of the line, which is the point where the line intersects the y-axis.
Then, we can rewrite our equation:
x + 2y = 16
to:
2y = 16 - x
y = (16 - x)/2
y = (-1/2)*x + 8
Comparing with the general line equation, we can see that the slope is -1/2.
