The price of two kilograms of sugar and five kilograms of salt is $5.50. If a kilogram of sugar costs $1.50, then how much is the price of three kilograms of sugar and a kilogram of salt?
Thoughts? Step-by-step reasoning:
Two kilograms of sugar is priced at $1.50 x 2 = $3. Three kilograms of sugar is priced at $1.50 x 3 = $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 = $0.50. Hence, three kilograms of sugar and a kilogram of salt.s price is $4.50 + $0.50 = $5.
Thus, the answer is 5.
