Answer:
C
Step-by-step explanation:
When you move the decimal either to the right or the left, you change the value. To divide any number by 10, move the decimal point one place to the left. For example:
0.7
7
70
700
7,000
So, for any decimal, when you move the decimal point one place to the right, you multiply that number by 10.
Given:
Total number of parking spaces = 414
Area of lower level = 22x^2
Area of upper level = 20x^2
Compact car section = 12x
The total number of spaces in a parking garage = Area of lower level + area of upper level + area of compact car section.
Working equation:
414 = 22x^2 + 20x^2 + 12x
414 = 42x^2 + 12x
42x^2 + 12x - 414 = 0
solve for x
x1 = 3
x2 = -3.29
We can only use the positive value. Therefore, x = 3. The number of compact car parking spaces is 12x = 12 * 3 = 36 parking spaces
The complete data set is:
Lower level parking = 22x^2 = 198
Upper level parking = 20x^2 = 180
Compact parking space = 12x = 36
