Answer: $2906.17

Step-by-step explanation:

We know that the average of a data set is given by :-

[tex]\text{Average}=\frac{\text{Sum of all observations}}{\text{Number of observations}}[/tex]

From the given data, the average monthly expenditure is given by :-

[tex]\text{Average}=\frac{\text{3,156.00 +2,896.50+2,666.00}}{3}=\frac{8718.5}{3}=2906.16666667\approx 2906.17[/tex]

Hence, her average monthly expenditure to the nearest penny = $2906.17
