PROBLEM # 1 AA steel beam, 715 cm long, is cut into two pieces so that one piece is 80 cm longer than the other. Find the length of each piece.
SOLUTION # 1
PROBLEM # 2 A solution that is 10% anti-freeze is mixed w/ a 20% anti-freeze to produce 50L of solution that is 15.6% anti-freeze. How many litres of the 10% solution are used? The total amount of solutions is 50 L
SOLUTION #2 The anti-freeze in the mixture comes from the anti-freeze in each solution.
SOLUTION #2.1 Strength of solution Litres of solution = Litres of Anti-Freeze 10% Solution0.10s= 0.10s 20% Solution0.20(50-s)= 10 – 0.20s 15.6% Mixture0.15650= 7.8
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.
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?
SOLUTION #3 Solution: 60 + x < 300 60 – 60 + x < 300 – 60 x < 240 Answer: P240
ANSWER To find the greatest amount of money Emanuel Josh can spend on the different boots Let x= the amount of money that he can spend on the different boots Cost of Riding a Roller Coaster PlusCost of different booths Less Than or Equal to Total Amount 60+X<300
