Question 5

Explanation

To determine the amount of bread obtained by Team A, we must relate all variables to the total bread availability.

The first step is to find the Total Bread distributed. Information $(4)$ states that one box contains $20$ packs. Since there are $3$ boxes, we can calculate the total:

Next, we need to separate Team D's share to find the remaining bread for Teams A, B, and C. Information $(3)$ mentions Team D gets one-third of the total.

The remaining bread for Teams A, B, and C is $60 - 20 = 40$ packs. Now we need their distribution ratios:

• Information $(1)$ states $A = \frac{1}{2}B$ or $B = 2A$.
• Information $(2)$ states $B = C$, so $C = 2A$.

By substituting these relationships into the remaining bread equation $A + B + C = 40$, we get:

Therefore, we need all information $(1)$, $(2)$, $(3)$, and $(4)$ to determine the amount of bread Team A obtained.
