First Semester DP Update
One topic where I feel as though I have shown the most growth would be working with percentages. Some examples of the work we did with percentages would be slopes involving rise/run when looking at hills as well as combining percentages with values such as combining a waiter's wages along with his tips when given the customer's bills for that time period.
One activity that really helped me understand percentages was problem 4 in Exploration 5. In this problem I had to as I said earlier, find out how much money a waiter made in one night solely from tips when given his wages as well as the total amount of money he earned that night. For this problem I simply subtracted his wages from the customer's bills. After this I divided that amount by the percent of the tips he got that night.

Another problem in the exact same exploration, problem 1 in exploration 5, helped me learn more about working with percentages in a different light. In this problem, I had to find an elevation loss given a percentage over a distance. The problem read as follows, You see a sign that says “7% grade next 6 miles.” How much elevation are you about to lose? Given this information, I divided the percentage by the distance and I got an altitude loss of 2217.6 feet. I simply converted my answer in miles into feet, which was .66. This problem and this exploration in general I feel was one of the most well created throughout the semester.
By the time practice 13 had come along, I feel as though I had mastered percentage work by this point and for the first problem of this practice I feel as though I did very well. The problem was a question regarding growth in a population. I knew I was gaining at a rate of 1.54 percent per year so I simply plugged that into my knowledge of pbkt equations and using my knowledge of where to place the percent I was able to make my equation calculate the population at any given year if the growth rate stays the same.
Spreadsheet Workshop Project
In this project we had to create various equations to solve for various prompts. I partnered with Corry Arcomano for this project.
