Let's determine the average amount Sarah saved per month over the specified six months.

First, add up Sarah’s savings for each month:
- September: [tex]$135.00 - October: $[/tex]144.00
- November: [tex]$104.00 - December: $[/tex]80.00
- January: [tex]$90.00 - February: $[/tex]160.00

To find the total savings over the six months, sum these amounts:
[tex]\[ 135.00 + 144.00 + 104.00 + 80.00 + 90.00 + 160.00 = 713.00 \][/tex]

Next, to find the average savings per month, divide the total savings by the number of months, which is 6:
[tex]\[ \frac{713.00}{6} = 118.83333333333333 \][/tex]

Rounding to two decimal places, the average savings per month is:
[tex]\[ 118.83 \][/tex]

Therefore, the best answer from the choices provided is:
d. \$118.83
