Sample Problems for Section 3.3 Write an equation to represent each of the following word problems. Solve each problem. Express answers as fractions or decimals when appropriate. Chloe has twice as many cats as her sister has dogs. Her brother has two turtles. Together, they have five pets. How many of each pet do they have? Brian is three times older than Sydney. The sum of the ages of Brian and Sydney is eight. How old is Brian? Samantha is 8 and two-third years older than Jason. The sum of their ages is 23 years. How old is Jason? Explain the meaning of the following equation that matches the given situation: I go to a department store with a coupon for 30% off any one item. The pants that I want are on sale for 40% off. What was the original price if I pay $21? Write an equation to represent each of the following real-life percent problems. Solve each problem. Express answers as fractions or decimals when appropriate.
