a college lab paced two orders with a chemical supplier. the first order was for 13 bottles of calcium hydroxide solution and 4 bottles of sulfuric acid and totalled $ 487. the second order was for 6 bottles of calcium hydroxide solution and 2 bottles of sulfuric acid and totalled $232.the bills do not list per item price.what were the costs of one bottle of calcium hydroxide solution ad one bottle of sulfuric acid?

Answer 1

The trick to these problems is just setting up the equations:

13c + 4s = 487
6c + 2s = 232

Now you can forge ahead
