Solving Word Problems Putting Your Translation Skills To Work

Let’s Make A Plan Verbal Model Ask yourself what you need to know how to solve the problem. Labels This means define the variable Algebraic Model Write a math equation or inequality using your labels and verbal model Solve Check to make sure your solution makes sense

Let’s Try Together You and some friends are at a Chinese restaurant. You order several $2.00 plates of wontons, egg rolls, and dumplings. Your bill is $25.20, which includes tax of $1.20. Use modeling to find out how many plates you ordered. Start with a verbal model. What do you know about buying food in the restaurant and how you find your bill.

Verbal Model Cost of food + tax = amount paid How do you determine cost of food? Each plate costs $2.00 so # of plates  $2.00 = cost of food Final verbal model $2.00  # of plates + tax = amount paid

Labels X = number of plates you purchased 2 = amount paid per plate 1.20 = tax paid on food = amount paid for food and tax

Algebraic Model Substitute the labels for the words in the verbal model $2.00  # of plates + tax = amount paid 2x = 25.20

Solve it and Check your answer 2x = x = x = There were 12 plates of food ordered 2(12) = ? = √

Pratice Workbook Page 17 Verbal Model $8 per hat has to equal $2480 Labels 8 = cost of one hat x = number of hats 2480 = amount they want to make Algebraic Model 8x = 2480 Solution x = 310 hats Check 8  310 = 2480 √
