Sandi had $600. She spent half of it at a farmer's market. Gillian spent $150 more than three times Sandi's total. What is the total that Gillian spent at the farmer's market? Think carefully first, then make a decision:
Sandi spent 600 / 2 = 300 dollars at the farmer's market. Gillian spent 300 * 3 + 150 = 1050 dollars at the farmer's market. So, the answer is 1050.
