Let C = cost to rent each chairLet T = cost to rent each table
4C + 8T = 73
2C + 3T = 28
Multiply the 2nd equation by (-2) and then add the equations together
4C + 8T = 73
-4C - 6T = -56
2T = 17T = 17/2 = 8.5
Plug this in to the 1st equation to solve for C
4C + 8(17/2) = 73
4C + 68 = 73
4C = 5C = 5/4 = 1.25
So the cost to rent each chair is $1.25 and the cost to rent each table is $8.50

Two buckets of seawater contain 
kg of salt.
Step-by-step explanation:
Amount of salt in 1 kg water = 
It is given that;
1 liter = 
500 liters = 
500 liters = 548 kilogram
As,
1 kg of seawater = of salt
548 kilograms = 
548 kilograms = kilograms of salt
Two buckets of seawater contain kg of salt.
