Final answer:
To calculate Caleb's GPA, convert his grades into a numerical scale and average them. Caleb's GPA is 3.25, rounded to two decimal places.The correct option is D.
Step-by-step explanation:
To calculate Caleb's GPA, we need to convert his grades into a numerical scale. Typically, letter grades are assigned a numerical value on a scale of 4.0. For example, an A is usually a 4.0, a B is a 3.0, and so on. Once we have the numerical values for Caleb's grades, we can calculate his GPA by taking the average.
- Math: 92 (equivalent to 4.0 on the scale)
- English: 85 (equivalent to 3.0 on the scale)
- History: 78 (equivalent to 2.0 on the scale)
- Science: 94 (equivalent to 4.0 on the scale)
Add up the numerical values: 4.0 + 3.0 + 2.0 + 4.0 = 13.0. Divide this sum by the number of grades (4) to get the average: 13.0 / 4 = 3.25.
So Caleb's GPA is 3.25, rounded to two decimal places. Therefore, the correct answer is D. 90.75.
