Answer 2

Answer: Average of her phone bill was $80.

Explanation:

Since we have given that

Maria's phone bills were

`\$95,\$67,\$43,\ and\ \$115.`

Average of her phone bills were given by

`Mean=\frac{\text{ Sum of total observation}}{\text{Number of observation}}\\\\Mean=(95+67+43+115)/(4)\\\\Mean=(320)/(4)\\\\Mean=\$80`

Hence, Average of her phone bill was $80.
