My question is: Emily bought a shirt and a coat for $600. What does the shirt cost if it is one-third the price of the coat? Your thoughts:
Let X be the price of the shirt. The price of the coat is X * 3. The total amount is X + X * 3 = $600. Combining like terms, we get X * 4 = $600. Dividing both sides by 4, we get X = $600 / 4 = $150. The final answer: 150.
