Answer:
Jayce's fee (in dollars) for 10th drive on a certain day is K.
Step-by-step explanation:
It is given that M(n) models Jayce's fee (in dollars) for nth drive on a certain day.
We need to find the meaning of M(10)=K.
On comparing M(n) and M(10), we get the value of n is 10.
Since M(n) represents the Jayce's fee (in dollars) for nth drive on a certain day, therefore, M(10) represents the Jayce's fee (in dollars) for 10th drive on a certain day.

It means Jayce's fee (in dollars) for 10th drive on a certain day is K.
1 gallon = 128 fluid ounces
2.5 gallons = 2.5 x 128 = 320 fluid ounces
Steve's boat uses 50 fluid ounce of fuel to 1 fluid ounce of oil, thus
for 320 fluid ounce of fuel it will use 320/50 = 6.4 fluid ounce of oil.
