Leila went to the supermarket to get some groceries. Then she headed to her mechanic to get her automobile fixed. If fixing her automobile cost $350 which was $50 more than thrice the amount she spent at the supermarket, how much has she spent altogether? Give me reasons, before answering the question

Reversing the steps to obtain the amount she spent at the supermarket, $50 less than $350 is $350 - $50 = $300. If $300 was thrice the amount she spent at the supermarket, then the amount spent at the supermarket was $300 / 3 = $100. In addition to what she spent fixing her auto, she spent $100 + $350 = $450 altogether. So the final answer is 450.
