In order to translate your SAT word problems into actionable math equations you can solve, you’ll need to understand and know how to utilize some key math terms. Train yourself to use these four steps to stay on track and continually work toward a solution. The SAT has many ways of making various stages of a word problem more difficult, which is why it is so important to have a good process. These are the two equations you have to work with: r + p = 7 31 = 5p + 4r Use the equations to solve for the desired value. Total Cost of Box = $31 Cost of Premiums = (5 $/pound) x (p pounds) = 5p Cost of Regulars = (4 $/pound) x (r pounds) = 4r 31 = 5p + 4r.

The total cost of the box is equal to the cost of the premium chocolates plus the cost of the regular chocolates. The other relationship concerns the total cost of the box. If the box contains only regular and premium chocolate, then you can write the following equation: Barrett bought a 7-pound box of chocolate. One fairly straightforward relationship concerns the total number of pounds of chocolate. Identify relationships and translate them into equations. In this question, there are two basic unknown values: the number of pounds of premium chocolate and the number of pounds of regular chocolate. Identify unknown values and label them with variables. The question asks for the number of pounds of premium chocolate that Barrett bought. If Barrett buys a 7-pound box of chocolates that costs him $31, how many pounds of premium chocolates are in the box? In essence, you need to turn a word problem into a system of equations and use those equations to solve for the desired value.Įxample: A candy company sells premium chocolate at $5 per pound and regular chocolates at $4 per pound.
Identify relationships and translate them into equations.Identify unknown values and label them with variables.Identify what value the question is asking for.Almost any word problem can be broken down into four steps: Though the actual math topics can vary, it is important to develop a consistent process for answering them. About 35% of your total questions on the Math Section will be made up of word problems.
