Suppose that your doctor recommends that you increase your daily intake of certain vitamins and minerals. For each recommendation described State the percent change in daily intake. State the number by which we can multiply the original daily intake to find the new daily intake. Find the new recommended daily intake. Your original Vitamin D intake was 7 micrograms and the doctor recommended you decrease your intake by 54%. Percent change in daily intake % The number we can multiply the original daily intake to find the new daily intake The new recommended daily intake amount Your original potassium intake was 1340 micrograms and the doctor recommended you increase your intake by 135%. Percent change in daily intake The number we can multiply the original daily intake to find the new daily intake The new recommended daily intake amount Your original zinc intake was 33 micrograms and the doctor recommended you decrease your intake by 20%. Percent change in daily in

Solution

a) original intake = 7mg

Reduce intake by 54% i.e. , now intake is 46%

i) So, change in intake = - 54%

ii) Number we can multiply with original to found new intake = 0.46

iii) New intake = 7*0.46 = 3.22 micrograms

c) oiginal intake = 33 microgms

i) Percent change in intake = - 20% (try with -ve sign)

ii) We can multiply 33 with 0.8 to get new value

iii) New intake = 26.4 milligrams
