Answer:
Samantha worked 26 hours and Adriana worked 13 hours.
Step-by-step explanation:
Let s = the number of hours that Samantha worked
Let a = the number of hours that Adriana worked
s = 2a
s + a = 39
2a + a = 39
3a = 39
a = 13
Work out 8% of 30000
10% of 30000 is 3000
1% of 30000 is 300
2% of 30000 is 300x2=600
Therefore 10%-2%= 3000-600=2400
It therefore follows that Mayra earned 4540 + 2400 = 6940 for January
