Leya [2.2K]

Let T be total number of milligrams of vitamin C in our salad.

We have been given that there are s milligrams of vitamin C per milliliter of spinach, B mg per milliliter of berries, and D mg per milliliter of dressing.

Let us find how much mg of vitamin C our each ingredient of salad will have.

We have been given that a salad contains 300 milliliters of spinach, 200 ml of berries, and 42 ml of dressing.  

\text{Mg vitamin C in 300 ml spinach}=300\cdot\text{s mg}

\text{Mg vitamin C in 200 ml berries}=200\cdot\text{B mg}

\text{Mg vitamin C in 42 ml dressing}=42\cdot\text{D mg}

To find total milligrams of vitamin C in our salad we will add milligrams of vitamin C in each of three ingredients of salad.

T=(300s+200B+42D)\text{ mg}

Therefore, our desired expression will be T=(300s+200B+42D)\text{ mg}.
