Question

Kayson mixes 300 milliliterss of spinach, 200 mL of berries, and 42 mL of dressing to make a salad. There are sss milligrams of vitamin C per milliliter of spinach, B mg per milliliter of berries, and D mg per milliliter of dressing. Which expressions can we use to describe how many milligrams of vitamin C are in the salad?

Answer 1

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

Answer 2

Answer:

300s+200b+42d and 200b+(300s+42d)
