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

A 600-ft tall building is represented by a 30-in. tall model.
alexdok [17]

\huge\boxed{19\ \text{inches}}

First, find the scale factor by dividing the first building's real-life height by its model height.

\frac{600}{30}=\frac{60}{3}=20

Now, we'll write an equation to find the model height of the second building.

r=20m

Here is an equation where r represents the real-life height of a building, 20 represents the scale factor, and m represents the model height of the same building.

Fill in the information we already know.

380=20m

Divide both sides by 20.

\frac{380}{20} = \frac{20m}{20}

\large{\boxed{19}}=m

So, the model height of the second building is 19 inches.
