Max Maths, Year 6, Try it, Word problems (2)

In a practical application of mathematics, Year 6 students are presented with a word problem involving the calculation of change from a purchase. Tya has bought 9 kg of fish, with each kilogram costing $8.70, and she pays with a $100 note. To solve the problem, students need to first calculate the total cost of the fish. This is done by multiplying the cost per kilogram by the number of kilograms purchased, which is $8.70 multiplied by 9 kg. Once the total cost is determined, students then subtract this amount from the $100 paid by Tya to find out how much change she should receive from her purchase.

The process involves two key mathematical operations: multiplication to find the total cost, and subtraction to calculate the change received. After working out the total cost of 9 kg of fish at $8.70 per kg, students subtract this total from the initial $100 to arrive at the final answer, which is the amount of change Tya receives. This exercise not only tests the students' arithmetic skills but also helps them to understand real-life applications of math in everyday situations, such as shopping and financial transactions.
