Application/Modeling/Problem-Solving Questions

Application/modeling/problem-solving questions require students to understand mathematical concepts and principles and be able to apply them to new situations.

Elizabeth selects 3 books for her niece. Each book costs $3.69. Elizabeth must also pay 4% sales tax on her purchases. How much change will she receive if she gives the store clerk $15.01?

1. $0.25
2. $3.50
3. $3.69
4. $11.07
5. Not enough information is given.

Answer: (2) $3.50 This problem requires the student to solve a multi-step problem by finding 4% of the total purchases and adding the sales tax to the cost of the books. The student should then subtract the total amount from $15.01.
