Each muffin costs about .88 cents since you do the unit rate and then you multiply both numerator and denominator by 12 which gets you $10.56. Therefore, for twelve muffins it costs $10.56 and per muffin it’s .88 cents

Answer:
$1.80, 2.90, 4.00, 10.90
not proportional
Step-by-step explanation:
For some distance d, we have a charge f(d) that is ...
![f(d)=\begin{cases}1.00&0\le d\le0.1\\1.00+0.10\cdot\dfrac{(d-0.1)}{0.10}&0.1](https://tex.z-dn.net/?f=f%28d%29%3D%5Cbegin%7Bcases%7D1.00%260%5Cle%20d%5Cle0.1%5C%5C1.00%2B0.10%5Ccdot%5Cdfrac%7B%28d-0.1%29%7D%7B0.10%7D%260.1%3Cd%5Cend%7Bcases%7D)
for d > 0.1, this simplifies to d +0.9.
Then the charges are ...
![\begin{array}{cc}\underline{\text{miles}}&\underline{\text{charge}}\\9/10&1.80\\2&2.90\\3\ 1/10&4.00\\10&10.90\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bcc%7D%5Cunderline%7B%5Ctext%7Bmiles%7D%7D%26%5Cunderline%7B%5Ctext%7Bcharge%7D%7D%5C%5C9%2F10%261.80%5C%5C2%262.90%5C%5C3%5C%201%2F10%264.00%5C%5C10%2610.90%5Cend%7Barray%7D)
The different relation for the first 1/10 mile indicates ...
the relationship is not proportional.
3 gallons x 4 qt/gallon = 12 quarts total.
He used 9, so he has 12 qt. - 9 qt. remaining.
3 Quarts remain.
