Two kilograms of sugar is priced at $1.50 x 2 = $<<2*1.5=3>>3.
Three kilograms of sugar is priced at $1.50 x 3 = $<<3*1.5=4.50>>4.50.
So five kilograms of salt is priced at $5.50 - $3 = $2.50.
Thus, a kilogram of salt is priced at $2.50/5 = $<<2.5/5=0.50>>0.50.
Hence, three kilograms of sugar and a kilogram of salt.s price is $4.50 + $0.50 = $5.
