Question
Some word problems have only one unknown value. In such cases, it is best to assign a variable to that unknown value, translate the word problem into a single mathematical equation, and then solve for the variable. Single-step word problems Part A Julia spent $52 on a book. The cost of the book was $20 less than twice what she spent on a backpack. How much did the backpack cost? Express your answer numerically in dollars. > View Available Hint(s) dollars Submit Multistep word problems Word problems are more complicated with two or more unknown values. First, assign a variable to each unknown value. The word problem should then be translated into the appropriate number of mathematical equations, which can then be solved by substitution. Keep in mind that the number of mathematical equations needed is equal to the number of variables. Consider the following multistep word problem: The sum of the ages of a brother and sister is 21. If four times the brother's age is subtracted from three times the sister's age, the difference is 14. Start by writing a separate equation for for each sentence. P Pearson on Education Inc.
