An electronics store had a special sale on two different models of calculators. The more high-tech model sold for $33.04 and the older model sold for $16.88. All together, 29 calculators were sold. Total sales came out to $731.92. Which system of equations can be used to determine how many high-tech models were sold, x, and how many older models were sold, y?


A. 16.88y = 33.04x + 29
x + y = 731.92


B. 33.04x + 16.88y = 731.92
x - y = 29


C. 33.04x + 16.88y = 29
x + y = 731.92


D. 33.04x + 16.88y = 731.92
x + y = 29
