hello! for question 24, miss tan can only spend up to$25. what we do is we write out the multiples of 3 so we know what is the maximum amount she can spend in multiples of 3. the answer is 24. 24 equals to 8 packets. to find the oranges, 8 packets x 4 oranges.

question 25, convert to centimetres first then divide by the length mrs chua wants.

let me know if you need further explanation ok! :)
