Solution Steps

To determine the revenue generated by selling 38 calculators, we can use the given formula \( R = 11.45 \times q \), where \( q \) is the number of calculators sold. By substituting \( q = 38 \) into the formula, we can calculate the revenue.

Step 1: Define the Revenue Formula

The revenue \( R \) generated by selling \( q \) calculators is given by the formula: \[ R = 11.45 \times q \]

Step 2: Substitute the Number of Calculators Sold

To find the revenue when \( q = 38 \), we substitute \( 38 \) into the formula: \[ R = 11.45 \times 38 \]

Step 3: Calculate the Revenue

Calculating the above expression gives: \[ R = 11.45 \times 38 = 435.1 \]

Final Answer

The revenue generated by selling 38 calculators is \(\boxed{R = 435.1}\).
