Which of the descriptions is true.

Solution

1. 14h represents the total charge for Krystal Klean Painting (NO—see the given statements)
2. 23h represents the total charge for Elegance Home Painting (YES)
3. 175 +14h +23h represents the total cost of painting (NO—in general, we expect one contractor to be hired, not both. This is the cost if both were working at once.)
4. For h=10 Elegance Home Painting is cheaper (YES—EHP charges $230; KKP charges $315)
5. For h=20, KKP is cheaper (YES—EHP charges $460; KKP charges $455)
