A glass bottle filled with oil Weighs 590 grams. After Sophia uses 200 milliliters of oil, the bottle of oil weighs 400 grams.

The weight M Of the bottle of oil in grams is a function of V The volume in milliliters Of oil Sofia has used

Write the functions formula?

• M = 590 - 20 V

• M = 400 + 20 V

• M = 590 - 0.95 V

• M = 400 + 0.95 V
