Answer:
The number of gallons must be greater than or equal to 6,500
Step-by-step explanation:
Let
x -----> the number of gallons of paint need to sell
we know that
The number of gallons multiplied by $10 minus the cost of the new graffiti must be greater than or equal to $50,000
so
The inequality that represent this situation is
[tex]10x-15,000\geq 50,000[/tex]
Solve for x
Adds 15,000 both sides
[tex]10x\geq 50,000+15,000[/tex]
[tex]10x\geq 65,000[/tex]
Divide by 10 both sides
[tex]x\geq 6,500[/tex]
The number of gallons must be greater than or equal to 6,500
