The expression 7(2B+J) describes how much Donovan spends on breakfast in one week. What does 2 B represent in the expression? A. Amount Donovan spends on breakfast each day. B.

Answer 1

Answer:

The correct answer is B. Amount Donovan spends on granola bars each day

Step-by-step explanation:

This is because we set the variable B as the cost of a granola bar. Since he eats two a day, we know that he pays for 2B each day

Answer 2

Answer:

B. Amount Donovan spends on granola bars each day.

Step-by-step explanation:

B is the price of a granola bar, so 2B is the price of two granola bars. Donovan eats 2 granola bars each day, so if he buys them, he spends 2B per day on granola bars.

Comment on the problem wording

Please be aware that the problem statement tells you only that he eats 2 granola bars each day. It does not tell you the relationship between Donovan's eating and Donvan's spending. The question asks about his spending, so there is insufficient information unless we make the assumption they are directly related.
