Answer:
105 mg
Explanation:
Given that:
1 baked potato provides 30 mg of vitamin C.
So,
70 baked potatoes provide [tex]30\times 70[/tex] mg of vitamin C
Also,
70 potatoes = 20 lb
So,
20 lb potatoes provide [tex]30\times 70[/tex] mg of vitamin C
Thus,
1 lb potatoes provide [tex]\frac {30\times 70}{20}[/tex] mg of vitamin C
Thus, 105 mg of Vitamin C are provided per pound of the potatoes.
