Answer:
T = 4B + 10C
Explanation:
Number of doughnuts a bag can hold = 4
Number of doughnuts a carton can hold = 10
Number of doughnuts in B bags = 4 × B = 4B
Number of doughnuts in C cartons = 10 × C = 10C
Total number of doughnuts bought by Tom = 4B + 10C
T = 4B + 10C
Hence, a formula in terms of T is T = 4B + 10C.
