40 ! cole needs to include at least 11 mg and at most 22 mg of iron in his diet each day. cole plans to eat multiple bananas daily, and each banana has 0.3 mg of iron. cole will get the rest of his iron from vitamins. each whole vitamin contains 4 mg of iron.
part a: if cole eats 3 bananas each day, what is the least number of whole vitamins he must take in order to stay within his daily iron requirement? what is the greatest number of whole vitamins he can take in order to stay within his daily iron requirement? use inequalities to solve.
part b: cole continues to eat 3 bananas each day. he pays $2 for every 3 bananas he buys. his first 10 vitamins are free, but if he purchases more than 10 vitamins in 1 week, he pays an additional dollar for every 2 additional vitamins he purchases.
