Answer:

During 3rd week, she earned $100, during second week she earned $40 and during 1st week she earned $60.

Step-by-step explanation:

Let money she earned in 1st week be x, 2nd week be y and 3rd week be z.

z = 60+y

z = 40+ x

now,

60+y = 40+ x

or, y = 40+x-60

or, y = x-20

Now,

x + y + z = 200

or, x + x - 20 + 40 + x = 200

or, 3x + 20 = 200

or, 3x = 180

so, x = $60

Now,

y = x-20

or, y = 60-20

so, y = $40

Now,

z = 60+y

or, z = 60+40

so, z = $100
