Can you use 2 percent milk and cream to make whole milk?

No, you need at least around 30% cream (milkfat), to be able to whip it. This usually means you need at least a light whipping cream, although most will prefer heavy whipping cream, as it's more reliable and stable. It is possible for certain light creams (not whipping cream) to have enough fat to whip, but they usually fall in at around 20% fat.
