After getting 5 new rocks, George gave half of his rock collection to Susan. If George gave Susan 36 rocks, which equation could be used to determine how many rocks George started with?

One-half x = 36 + 5
One-half (x minus 5) = 36
One-half (x + 5) = 36
One-half x + 5 = 36

One-half (x + 5) = 36

Reason: George started with x, after getting 5 he had x + 5, and he gave half of that to Susan, so (1/2)(x + 5) = 36. (Solving gives x + 5 = 72, so x = 67.)
