<PRE><B>Question 139477</B>
Two girls went to the store for rice and sugar. One girl bought 3 kilograms of sugar and 2 kilograms of rice for $3.25. The other girl bought 2 kilograms of rice for $2.50. Find the price per kilogram for both the sugar and rice.
--------------
3s + 2r = 325 cents
2r = 250 cents
------------------
r = 125 cents (rice is $1.25 per kg)
Substitute to solve for s:
3s + 250 = 325
3s = 75
s = 25 cents (sugar is $0.25 per kg)
