Instructions: Create an algorithm to solve the problems below. Be as precise as possible.
1. John has a big test next week. He wants to do well, but he has trouble focusing. Some of the elements on the test are easy to memorize, but some have formulas. Create a method for John to study for the test.
2. Michael wants to build a sandbox for his daughter and son. He does not want it to take up the whole yard, but he does want the two kids to fit in it. His son is 3 feet 4 inches and his daughter is 2 feet 5 inches. Because they always fight, he wants at least one foot between both kids in the sandbox. His backyard is 7 feet wide and 7 feet long. What would be Michael's best option?
3. Tracy just opened a new business. She has 2 friends who are willing to assist her. Each friend agreed to receive 12.4% of the profit of all sales. Tracy wants to get 30% of the sales. However, her overhead is about 29.5% of the product cost and the website costs 10% of the cost. She also has to pay for rent, lights, and water, which is 30% of the business profits. If Tracy makes $300 per order and she has 5 orders, how much will each cost get, and what would be Tracy's percentage?
