Question 686969: A chemist has two large containers of sulfuric acid solution, with different concentrations of acid in each container. Blending 305 mL of the first solution and 595 mL of the second gives a mixture that is 12.76% acid, whereas blending 95 mL of the first mixed with 480 mL of the second gives a 9.81% acid mixture. What are the concentrations of sulfuric acid in the original containers? (Round your answer to the nearest whole number.)
What is the percent of the first solution???

--------
acid + acid = acid
x*305 + y*595 = 0.1276(305+595)
x*95 + y*480 = 0.0981(95+480)
-----
Solve for x and y using a matrix TI-84 calculator method
---
x = 0.2398.. = 24%
y = 0.070.. = 7%
=====================
