The total number of parking spaces in a parking garage is calculated by adding the area of the lower level given by 22x2, the ar
ea of the upper level given by 20x2, and a compact car section given by 12x for a total of 414 parking spaces. Which equation could be used to solve for the number of compact car parking spaces?
A) 22x2 − 20 x2 − 12x = 414
B) 22x2 − 20 x2 + 12x = 414
C) 22x2 + 20 x2 − 12x = 414
D) 22x2 + 20 x2 + 12x = 414
A) 22x2 − 20 x2 − 12x = 414
B) 22x2 − 20 x2 + 12x = 414
C) 22x2 + 20 x2 − 12x = 414
D) 22x2 + 20 x2 + 12x = 414
