Answer:
why are you mad just show me where it is :(
Step-by-step explanation:
They received 3,088 calls.
3,860 -> 3,088
|———————|
100% -20% 80%
Cross multiply 3,860 by 80 and divide by 100 to get 3,088
The value of 3 in 3,456 is 3000 and the value of the 3 in 546,300 is 300 so you would multiply 3000*300 if I am correct.
I hope this could help.

Answer:
6 years
Step-by-step explanation:
So each person's age can be represented as a linear equation, since each year our age increases by 1. It can be represented in the slope-intercept form: y=mx+b. The slope in this case is going to be 1, since the time is going to be years, and each year everyone's age goes up by 1 (of course if you're still alive...) and y-intercept in this case represents their current age.
So the father can be represented as: y=x+38
The sons can be represented as: y = x+13 and y=x+5
The daughter can be represented as: y=x+8
So adding up all his children you get:
(x+13)+(x+5)+(x+8)
This gives you the equation:
3x+26
Now set this equal to the father's age to solve for x (in this context it's years)
3x+26=x+38
Subtract from both sides
2x+26=38
Subtract 26 from both sides
2x=12
Divide both sides by 2
x=6
So in 6 years the father will be the same age as his children put together
