Could you advise how to solve this question? Kindly guide on the model drawing too. Thanks!
The question is: A watch costs $25 more than a calculator. 3 such watches cost as much as 8 such calculators. What is the cost of each calculator?
Step 1: This question involves the Comparison Concept and the Repeated Variable Concept. Since A watch costs $25 more than a calculator, we draw 1 box to represent the amount of money a calculator cost and draw an identical box plus another box marked with "$25" to show that the watch cost $25 more than a calculator.
