write a formula to determine the percent change for each of the following. use the left side of the equation to indicate in which cell to store the formula.
a. apple inc. text box ×
b. cooper tire & rubber co. text box ×

Explanation:

Response
Part a: Apple Inc. (Row 2)

Step1: Recall % Change Formula

The formula for percentage change is $\text{\% Change} = \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \times 100\%$. For Apple, the new close (February 25) is in cell C2, old close (February 24) is in cell F2. So the formula in cell E2 (where % Change is stored) should be based on this.

Step2: Construct the Formula

To calculate the percentage change for Apple (row 2), the formula is $=\frac{(C2 - F2)}{F2} \times 100\%$. In spreadsheet terms (like Excel), this is =(C2 - F2)/F2 (the formatting to percentage will handle the % sign, but the calculation is $\frac{\text{New} - \text{Old}}{\text{Old}}$).

Part b: Cooper Tire & Rubber Co. (Row 4)

Step1: Identify Cells

For Cooper Tire (row 4), new close is C4, old close is F4. Use the same % change formula: $\text{\% Change} = \frac{\text{New} - \text{Old}}{\text{Old}} \times 100\%$.

Step2: Write the Formula

In cell E4 (where % Change is stored), the formula is $=\frac{(C4 - F4)}{F4} \times 100\%$. In spreadsheet syntax, this is =(C4 - F4)/F4.

Final Answers (Spreadsheet Formulas):

a. For Apple Inc. (cell E2): =(C2 - F2)/F2
b. For Cooper Tire & Rubber Co. (cell E4): =(C4 - F4)/F4

(Note: These formulas, when entered in Excel/Google Sheets and formatted as percentage, will give the correct % change. For example, for Apple: $(96.76 - 96.1)/96.1 \approx 0.006868 \approx 0.69\%$ when rounded to two decimals, which matches the concept of percentage change.)
