Olivia is painting a logo for a billboard and wants to use a combination of blue paint and red paint to completely cover a 5000
My name is Ann [436]

Answer:

($20/gal)r + ($30/gal)b ≤ $250

r + b ≤ 10 (gallons)

Step-by-step explanation:

Represent the amount of red paint by r and that of blue point by b.

Olivia must cover 5000 ft^2 with paint, which comes out to 5000/500, or 10, gallons total of red and blue paint.  The corresponding inequality is

r + b ≤ 10 (gallons)

She has onlyl $250 to spend.  Therefore, the following must hold true:

($20/gal)r + ($30/gal)b ≤ $250

The required sysstem of inequalities is thus

($20/gal)r + ($30/gal)b ≤ $250

r + b ≤ 10 (gallons)
