A company builds Electronic Entertainment Centers. It costs $8,700 to build 10 Electronic Entertainment Centers and $14,300 to build 20 Electronic Entertainment Centers. Which equation models the cost, C(x), as a linear function of the number of Electronic Entertainment Centers, x?

C(x) = 3100x − 560

C(x) = 560x − 3100

C(x) = 3100x + 560

C(x) = 560x + 3100
