How much do the apples cost? ** The apples cost Fabian 5 kg * $2/kg = $<<5*2=10>>10.
How much do the walnuts cost? ** For the walnuts Fabian needs to pay 0.5 kg * $6 = $<<0.5*6=3>>3.
How much does one pack of sugar cost? ** One pack of sugar costs $2 - $1 = $<<2-1=1>>1.
How much will Fabian pay for sugar? ** So Fabian will pay $1/pack * 3 = $<<1*3=3>>3 for sugar.
How much does Fabian need to pay? ** In total, Fabian needs to pay $10 + $3 + $3 = $<<10+3+3=16>>16.
