Question

(URGENT!! PLS HELP) The color of paint used to paint a race car includes a mixture of yellow and green paint. Scotty wants to lighten the color by increasing the amount of yellow paint 30%. If a new mixture contains 3.9 liters of yellow paint, how many liters of yellow paint did he use in the previous mixture?

Answer 1

• 3 liters

Explanation:

Let the initial amount of yellow paint be x

Then we have x increased by 30% equals 3.9 liters:

• x + 0.3x = 3.9
• 1.3x = 3.9
• x = 3.9/1.3
• x = 3 liters
