Three identical notches and four identical bends are required in the sheet metal operation.
In total 7 things are required in the metal operation.
We can think it as we need to put the 3 notches and 4 bends in 7 places.
First, lets put the 3 notches in 3 places.
In order to do so, we need to choose 3 places from the 7 places.
We can choose 3 places in

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
