Fabian is shopping at a nearby supermarket. He wants to buy 5 kilograms of apples, 3 packs of sugar, and 500 grams of walnuts. One kilogram of apples costs $2, and one kilogram of walnuts costs $6. One pack of sugar is $1 cheaper than one kilogram of apples. How much Fabian needs to pay for the items he wants to buy? Give me reasons, before answering the question

The apples cost Fabian 5 kg * $2 / kg = $10. For the walnuts Fabian needs to pay 0.5 kg * $6 = $3. One pack of sugar costs $2 - $1 = $1. So Fabian will pay $1 / pack * 3 = $3 for sugar. In total, Fabian needs to pay $10 + $3 + $3 = $16. So the final answer is 16.
