To determine the Earnings of Shelley last week, we need to make relations with the values that are given. We let x as the total amount she earned last week by x and y as the additional amount she earned this week We do as follows:
20% additional amount she earned this week = y / 72 - y
y = $ 12
x = 72 - 12 = $60 total earnings last week
1% of $3500 is $35
Double that means
2% is $70
So first year would be $3570
Now
1% of $3570 is $35.70
2% is $71.40
So second year would be
$3641.40
