Suppose that your doctor recommends that you increase or decrease your daily intake of certain vitamins and minerals. For each recommendation described, do the following: i. State the percent change in daily intake. ii. State the number by which we can multiply the original daily intake to find the new daily intake. iii. Find the new recommended daily intake. a. Your original Vitamin D intake was 7 micrograms and the doctor recommended you decrease your intake by 53%. i. Percent change in daily intake % ii. The number we can multiply the original daily intake to find the new daily intake: iii. The new recommended daily intake amount: micrograms b. Your original potassium intake was 1110 micrograms and the doctor recommended you increase your intake by 115%. i. Percent change in daily intake % ii. The number we can multiply the original daily intake to find the new daily intake: iii. The new recommended daily intake amount: micrograms c. Your original zinc intake was 48 micrograms and the doctor recommended you decrease your intake by 23%. i. Percent change in daily intake % ii. The number we can multiply the original daily intake to find the new daily intake: iii. The new recommended daily intake amount: micrograms d. Your original calcium intake was 720 micrograms and the doctor recommended you decrease your intake by 35%. i. Percent change in daily intake: % ii. The number we can multiply the original daily intake to find the new daily intake: iii. The new recommended daily intake amount: micrograms

Solution

1) a) original intake = 7 micrograms , doctor recommended to decrease amount by 53%

percentage change in daily intake = (7 - .53*7 ) / 7 * 100 = 47%

ii) Decrease by 53 %; Remaining = 47%

7 * .47 will give you new daily intake

iii) the new recommended daily intake amount = 7 - .53* 7 = 3.29micrograms

b) potassium intake was 1110 micrograms

doctor recommended to increase by 115%

i) percentage change = 15%

ii) new daily intake = 1110 + 1110*1.15 = 2386.5

so ,2.15 should be multiplied to get the new intake amount

iii) new intake amount = 2386.5 micrograms

c) original zinc intake = 48 micrograms

doctor recommended decrease by 23%

i) percentage change = (48 - 36.96)/ 48 * 100 = 23%

ii) .77 would be multiplied by original intake to get new intake

iii) new intake amount = 36.96 micrograms
