Answer 2

Answer:

160,140,120,100,80,60,40

Step-by-step explanation:

Let the first cash prize be x+60

Second cash prize = x+40

Third cash prize = x+20

Fourth cash prize = x

Fifth cash prize = x-20

Sixth cash prize = x-40

Seventh cash prize = x-60

∴ x+60+x+40+x+20+x+x-20+x-40+x-60 = 700

7x = 700

x=100

First cash prize = x+60 = 100+60 = 160

Second cash prize = x+40 = 100+40 = 140

Third cash prize = x+20 = 100+20 = 120

Fourth cash prize = x = 100

Fifth cash prize = x-20 = 100-20 = 80

Sixth cash prize = x-40 = 100-40 = 60

Seventh cash prize = x-60 = 100-60 = 40
