Chuck sold a box of 38 books at a yard sale for a total of $82.86. He sold the paperback books for $1.92 each and sold the hardcover books for $2.47 each. Which system of equations can be used to determine the number of $1.92 paperback books, x, and the number of $2.47 hardcover books, y, that were sold at the yard sale?

A. x + y = 38
2.47y = -1.92x + 82.86

B. y = x - 82.86
1.92x + 2.47y = 38

C. x + y = 38
1.92x + 2.47y = 82.86

D. 2.47x - 1.92y = 38
x + y = 82.86

A. 	  x + y = 38
  2.47y = -1.92x + 82.86

B. 	  y = x - 82.86
  1.92x + 2.47y = 38

C. 	  x + y = 38
  1.92x + 2.47y = 82.86

D. 	  2.47x - 1.92y = 38
  x + y = 82.86
