Answer:
$8 per hour
Explanation:
Total amount earned by Lily in two days = $54
Number of hours worked on day 1 = 2.5
Number of hours worked on day 2 = 4.25
Total number of hours worked in two days = 2.5 + 4.25 = 6.75
Let the amount earned by Lily per hour = x
Then
![\[6.75 x = 54\]](https://img.qammunity.org/2020/formulas/mathematics/high-school/mwmf0rt5dyudcmwxnx0oeuvdhkqbtngl5q.png)
=>
![\[x = (54)/(6.75)\]](https://img.qammunity.org/2020/formulas/mathematics/high-school/onv2qm4tiy7ximv1p8kofcktogrrvqo44l.png)
=>
![\[x = 8\]](https://img.qammunity.org/2020/formulas/mathematics/high-school/w7glhky0qp950tmjqrygegl6zrxi385943.png)
Hence the amount earned by Lily or Naomi per hour is $8.
