Worked Solution
Step 1: Find the transport cost.
"3 times as much on groceries as on transport" means: groceries = 3 x transport.
$48 = 3 x transport
transport = $48 / 3 = $16.
Step 2: Find the total amount spent.
Total spent = $48 + $16 = $64.
Step 3: Find how much Auntie Lim brought.
She brought twice as much as she spent: 2 x $64 = $128.
Answer: Auntie Lim brought $128.
Correct answer: $128
