Pavel [41]

The percent increase in iron = 50 %

Step-by-step explanation:

Initial amount of iron per serving = 1.2 mg

After an increase the amount of iron per serving = 1.8 mg

Increase in  the amount of iron per serving = 1.8 - 1.2 = 0.6 mg

Percent increase in iron is calculated as

% increase = \frac{Final amont - initial amount }{initial amount}Change = \frac{Final \ amount - initial \ amount }{initial \ amount} (100)

Put the values in above formula we get

\frac{0.6}{1.2} (100) =   50 %

Iteru [2.4K]

Answer:

\$36,945.28  

Step-by-step explanation:

we know that

The formula to calculate continuously compounded interest is equal to

A=P(e)^{rt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest in decimal  

t is Number of Time Periods  

e is the mathematical constant number

we have  

t=25\ years\\ P=\$5,000\\ r=8\%=8/100=0.08

substitute the values in the formula

A=5,000(e)^{0.08*25}  

A=5,000(e)^{2}  

A=\$36,945.28
