<u>Area of the frame with picture:</u>
<u>Area of the picture:</u>
<u>Area of the wooden frame is the difference of the above values:</u>

X= (300 s + 200 b + 42 d )mg
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
is the required expression
