Explanation Given Information: The provided expression is 1 3 8 − 1 2 × 3 4 + 1 5 8 ÷ 1 16 . Formula used: Steps for order of operations are as follows: Step 1. Initially operate operations within parenthesis or group symbols. Step 2: Evaluate powers of number. Step 3: Next, perform multiplication and division from left to right. Step 4: Finally perform addition and subtraction from left to right. Calculation: Consider the following expression: 1 3 8 − 1 2 × 3 4 + 1 5 8 ÷ 1 16 Initailly convert mixed fraction to improper fraction as follows: 1 3 8 = 8 × 1 + 3 8 = 8 + 3 8 = 11 8 And 1 5 8 = 8 × 1 + 5 8 = 8 + 5 8 = 13 8 Thus equation is, 11 8 − 1 2 × 3 4 + 13 8 ÷ 1 16 Using the order of operation, apply the steps to evaluate the expression

1. Iodine-131 is tone of the most commonly used radioactive isotopes of iodine. It is used to treat hyper- thyroidism and some kinds of thyroid cancer. (a) Iodine-131 has a half-life of about 8 days. Find an expression for I(t), the mass of Iodine-131 remaining after t days, in terms of t and Io, the initial mass of Iodine-131 present at time t = 0. (b) If a dose of 0.9 mg of Iodine-131 is administered, how much is still present after 24 hours? (c) How much Iodine-131 is present after one week? Does your answer make sense?

Question 2: When John started his first job, his first end-of-year salary was $82,500. In the following years, he received salary raises as shown in the following table. Fill the Table: Fill the following table showing his end-of-year salary for each year. I have already provided the end-of-year salaries for the first three years. Calculate the end-of-year salaries for the remaining years using Excel. (If you Excel answer for the top 3 cells is not the same as the one in the following table, your formula / approach is incorrect) (2 points) Geometric Mean of Salary Raises: Calculate the geometric mean of the salary raises using the percentage figures provided in the second column named “% Raise”.
