Answer:

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 %

Therefore the percent increase in iron = 50 %
