Kayson mixes 300 milliliters (mL) (mL) of spinach, 200mL of berries, and 42mL of dressing to make a salad. There are s s milligrams (mg) (mg) of vitamin C per milliliter of spinach, b mg bmg per milliliter of berries, and d mg dmg per milliliter of dressing. Which expressions can we use to describe how many milligrams of vitamin C are in the salad?

X = (300 s + 200 b + 42 d) mg

Step-by-step explanation:

Amount of spinach=300 ml

Amount of berries = 200 ml

amount of dressing = 42 ml

Vitamin C in one ml of spinach = s mg

Vitamin C in 300 ml of spinach = 300 s mg

Vitamin C in one ml of berries=b mg

Vitamin C in 200 ml of berries = 200 b mg

Vitamin C in one ml of dressing = d mg

Vitamin C in 42 ml of dressing = 42 d mg

Let total vitamin C be = x

Then

X = (300 s + 200 b + 42 d) mg

is the required expression
