An economics professor bases his final grade on homework, two midterm examinations, and a final examination. The homework counts 10% toward the final grade, while each midterm examination counts 25%. The remaining portion consists of the final examination. If a student scored 95% in homework, 70% on the first midterm examination, 96% on the second midterm examination, and 72% on the final, his final average is 79.8%.

To calculate the final average, we can use the following formula:

Final grade = (0.10 * Homework) + (0.25 * Midterm 1) + (0.25 * Midterm 2) + (0.40 * Final)

Substituting the given values, we get:

Final grade = (0.10 * 95) + (0.25 * 70) + (0.25 * 96) + (0.40 * 72)
Final grade = 9.5 + 17.5 + 24 + 28.8
Final grade = 79.8 %

Therefore, the given statement is true.
