Translate into an equation, then solve.Bob works as a salesman. He was told that he will get a bonus if he has 
in sales over a four-week period. The first week his sales were 
The second week his sales were $1820. The third week his sales were 
How much must Bob sell during the final week to get the bonus?
A. 2350 + 1820 + 3160x = 12,110; x = 
B. 2350 + 1820 + 3160 - x = - 12,110; x = 
C. 2350 + 1820 + 3160 + x = 12,110; x = 
D. 2350 + 1820 + 3160 = x + 12,110; x =
