Question: Mike is shopping at the mall. He needs to buy a shirt, a new wallet, and some food for the evening. The shirt costs a third of the value of the wallet. The wallet is $60 more than the cost of the food, on which Mike spent $30. How much did Mike spend that day on the shopping? Think carefully first, then make a decision:
The wallet costs $60 more than the food, so it's $30 + $60 = $90. So the cost of the shirt is 1 / 3 * $90 = $30. Mike spent that day $30 + $30 + $90 = $150. So the answer is 150.
