Answer:
The answer is 19.
Explanation:
To find out how many muffins Neveah and Clint have left to bake, subtract the number of muffins they've already baked from the total they need to bake:
Total muffins to bake - Muffins already baked
30 - (4 + 7)
Combine the muffins already baked:
30 - 11
Subtract:
19
So, Neveah and Clint have 19 muffins left to bake.
