Solution Dilution

If 200 mL of an 11% solution is diluted to 1500 mL what is the strength of the solution?

Here's the set-up: (equation)
(200mL)(.11%)+(1300mL)(.00%) = (1500mL)(X%)
Work out the math:
(200mL)(.11%)+(1300mL)(.00%) = (1500mL)(X%)
(200mL)(.11%) = (1500mL)(X%)
22 = 1500X
X = .0147
X = 1.5% (the solution is now 1.5%)
