Lara sells cakes and sandwiches. The daily cost of making cakes is $610 more than the difference between the square of the number of cakes sold and 40 times the number of cakes sold. The daily cost of making sandwiches is modeled by the following equation:

C(x) = 3x2 - 50x + 500

C(x) is the cost in dollars of selling x sandwiches.

Which statement best compares the minimum daily cost of making cakes and sandwiches?
