Final Answer:

a) 14 hours tutoring and 6 hours at Bill Miller's BBQ.

b) 12 hours tutoring and 8 hours at Bill Miller's BBQ.

c) 16 hours tutoring and 4 hours at Bill Miller's BBQ.

Step-by-step explanation:

To calculate the combinations of hours that will allow you to earn the specified amounts, we can set up equations based on the given hourly rates. Let t represent the tutoring hours and b represent the Bill Miller's BBQ hours.

a) For $150:


\[10t + 12b = 150\]

Subject to the constraints:


\[t + b \leq 20\]


\[t \geq 4\]

Solving these equations gives us
\( t = 14 \) and \( b = 6 \)
\( b = 6 \).

b) For $200:


\[10t + 12b = 200\]

Subject to the constraints:


\[t + b \leq 20\]


\[t \geq 4\]

Solving these equations gives ust = 12 and b = 8 .

c) For $180:


\[10t + 12b = 180\]

Subject to the constraints:


\[t + b \leq 20\]


\[t \geq 4\]

Solving these equations gives us t = 16 and b = 4 .

In summary, the combinations of hours that meet the criteria are:

a) 14 hours tutoring and 6 hours at Bill Miller's BBQ, earning $150.

b) 12 hours tutoring and 8 hours at Bill Miller's BBQ, earning $200.

c) 16 hours tutoring and 4 hours at Bill Miller's BBQ, earning $180.
