Answer:
C (32)
Step-by-step explanation:
12 sneakers / 9 boots = x sneakers / 24 boots
the ratio is 4:3 so divide 24 by 3 and multiply by 4
12 / 9 = (24 / 3 x 4) / 24
12 / 9 = 32 / 24

The side length (in feet) of the square window which has the cost of making equal to $355 is 30 feet.
<h3>What is a mathematical model?</h3>
A mathematical model is the model which is used to explain the any system, the effect of the components by study and estimate the functions of systems.
The cost (in dollars) of making a square window with a side length is C. the length of side of the window is n.
The model, which represent the cost of window in dollar, is,
C=(n²/5)+175
A window costs $355. Thus, C=355. Put this value in above model as,
355=(n²/5)+175
355-175=(n²/5)
180 x 5=n²
n=√(900)
n=30
Hence, the side length (in feet) of the square window which has the cost of making equal to $355 is 30 feet.

This would be a question that would involve division.
We do: (1,600 ÷ 4) and therefore, this would give us
just as we were looking for, and therefore,
B would be your correct answer.
