$2880

Roughly, $760 For Her 40 Hours Per Week 

$720=30hrs
$1    =    x
cross multiply
$720x=30hr
convert the hour to sec
30*60=1800min
therefore, to sec,=
1800*60=108000s
she takes 720ussd for 108000s
for 1 ussd=108000/720
she takes $1 for every 150 sec
for 40 hrs= 40*3600

$1 = 150
$x = 144000
x=960
she collects 960 ussd in 40 hours
