Answer:
It took Betty 1 hour 24 minutes to bake 1 cake.
Step-by-step explanation:
1) Convert to minutes. 4 hours 12 minutes = 252 minutes
2) Divide by 3 (number of cakes). 252 minutes divided by 3 is equivalent to 1 hour 24 minutes or 84 minutes.

f(2) = -f(1) +5 = -2 +5 = 3
f(2) = 3

Answer:
<u>The student's final score is 77.2 and he earned a C letter grade</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the math problem correctly:
Midterm = 5% of the final grade and score of 60
Class project = 10% of the final grade and score of 92
Set of homework = 35% of the final grade and score of 80
Final exam = 50% of the final grade and score of 74
2. What is the student's final score?
Final score = (60 * 0.05) + (92 * 0.1) + (80 * 0.35) + (74 * 0.5)
Final score = 3 + 9.2 + 28 + 37
Final score = 77.2 and letter grade of C
