Step-by-step explanation:

missing either x+8=0
x=-8
Answer:
x>=42
Step-by-step explanation:
multiply by 7 on both sides
Let the number of hours be $x
Initial charges by Sanford's Plus = $125
Per hour charges = $165
Total cost of Sanford's Plus company = 125 + 165x
Initial charges by Quality Moving Company = $200
Per hour charges = $145
Total cost of Quality Moving Company = 200 + 145x
If either company were hired for hours, the total cost would be the same
125 + 165x = 200 + 145x
Add -125 on both sides
125 - 125 + 165x = 200 + 145x-125
165x = 75 + 145x
Add -145 on both sides
165x - 145x = 75
20x = 75
Divide both side by 20, to find the value of x
x = 75/20
x = 3.75 hours
Total cost of Sanford's Plus company = 125 + 165x
x = 12 hrs
Total cost of Sanford's Plus company = 125 + 165(12)
Total cost of Sanford's Plus company = 125 + 1980
Total cost of Sanford's Plus company = $2105
