377 + 935 = 1312 Cupcakes Total.
(Vanilla + Chocolate = Total Cupcakes)
1312/24 = 54.6
(Total cupcakes/Number of cupcakes that can be made in a single pan = Number of times Georgia has to refill the pan.)
Georgia can refill her pan 55 times (Rounding up, because if you round down, then not all the cupcakes would be baked) to make the cupcakes she want.
