Answer:
Option d.$18 to $30
Step-by-step explanation:
we know that
The quartet earn between $25 and $40 per hour.
so
If they play for 3 hours
then
($25*3)=$75
($40*3)=$120
the quartet will earn between $75 and $120
Divide the money equally between the four members
$75/4=$18.75
$120/4=$30
therefore
Each member can make between $18.75 and $30
