Answer 1

t = 10b + 10c

Explanation:

As stated in the problem, 1 bag holds 10 doughnuts so that give us 10b since we don't know how many bags were bought/sold but we do know how many comes in each. Same goes for cartons.

Were asked to write a formula for t, and since we don't know how many bags(b) or cartons(c) were sold, our t remains t.
