8. Solution #2.1

9. solution # 2.2 • 0.10 s + (10 – 0.20s) = 7.8 • -0.10s + 10 = 7.8 • -0.10s = -2.2 -0.10 -0.10 • s = 22 L • 50-s = 28 L Let’s Check it. 

10. answer 22L of the 10% Solution is used to make the mixture

11. Problem # 3 • Emanuel Josh has P300 in his wallet. He wants to ride on a roller coaster and to enter into the different boots at the Star City. If the roller coaster cost P60, what is the most he can spend on the different boots?
