Let’s Make A Plan Verbal Model Labels Algebraic Model Solve 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 Final 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 25.20 = 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 + 1.20 = 25.20
Solve it and Check your answer 2x + 1.20 = 25.20 1.20 - 1.20 2x = 24.00 2 2 x = 12.00 There were 12 plates of food ordered 2(12) + 1.20 = 25.20 ? 24 + 1.20 = 25.20 √
