For a project, a builder purchased 7 boxes of bolts with each box containing 11 bolts. He purchased 3 boxes of nuts with each box containing 15 nuts. He ended up finishing the project 6 days early and with 3 bolts and 6 nuts left over. How many bolts and nuts did he use for the project? Give me reasons, before answering the question
The builder purchased 7 boxes * 11 bolts = 77 bolts. He used 77 bolts - 3 left over = 74 bolts for the project. The builder purchased 3 boxes * 15 nuts = 45 nuts. He used 45 nuts - 6 left over = 39 nuts for the project. Total for the project he used 74 bolts + 39 nuts = 113 nuts and bolts. So the final answer is 113.
