Answer:
(a) The monthly budget for housing would range from $2,291.50-$2,749.80.
the good estimate would be $2,566.48.
(b) The monthly budget for housing would range from $1,250-$1,500.
the good estimate would be $1,400.
Step-by-step explanation:
Explanation with steps are in the following attachment
1. Take an arbitrary point that lies on the first line y=3x+10. Let x=0, then y=10 and point has coordinates (0,10).
2. Use formula to find the distance from point
to the line Ax+By+C=0.
.
3. Since lines y=3x+10 and y=3x-20 are parallel, then the distance between these lines are the same as the distance from an arbitrary point from the first line to the second line.
Answer: .
