Final answer:
To rewrite the equation f s = 16 in terms of f, divide both sides of the equation by the cost of sugar per pound, which is $0.50. Simplify the equation to f = 32 pounds.
Step-by-step explanation:
To rewrite the equation f s = 16 in terms of f, we can divide both sides of the equation by the cost of sugar per pound. Since the cost of sugar per pound is $0.50, we have f = 16 / 0.50. Simplifying the division, we find that f = 32 pounds. Therefore, the equation f s = 16 can be rewritten in terms of f as f = 32.
