Answer: 17 patients stayed for longer than 10 minutes.
Step-by-step explanation:
Let x represent the number of patients that stayed for longer than 10 minutes.
The doctor charges $21.80 for consultations that last less than 10 minutes and $27.50 for those that last longer than 10 minutes. Yesterday the doctor earned $1077.90. If 28 consultations lasted less than 10 minutes, it means that
28 × 21.80 + x × 27.50 = 1077.90
610.4 + 27.5x = 1077.9
27.5x = 1077.9 - 610.4
27.5x = 467.5
x = 467.5/27.5
x = 17

Here we know that at 3:17 pm you started to bake the cake. The total revolution the minute hand on the clock makes is:
We know that:
Solving for x:
So it takes 70 minutes after you put the cake in the oven. But:
Adding this to the initial time:
Finally, the cake is done at 4:27 pm, option C.
Answer:
Absolute magnitude
