Select the equation that best represents this situation and solution.

A.120 + 12(30 + x) = 900; $35
B.120 + 12(30 + x) = 900; $420
C.120 + 12(30) + x = 900; $35
D.120 + 12(30) + x = 900; $420

Answer 1

A

Explanation:

120 + 12 ( 30 + x ) = 900 ; $35

Answer 2

The equation that best represents this situation is:
120 + 12 * ( 30 + x ) = 900
120 + 360 + 12 x = 900
12 x = 900 - 480
12 x = 420
x = 420 : 12
x = $35
Answer:
A ) 120 + 12 ( 30 + x ) = 900 ; $35
