Answer:
24 carbohydrates
Step-by-step explanation:
Represent Snack bars with S and Milks with M.
So, we have:
and
Required: Solve for M and S
Convert the given expressions to mathematical expressions:
--- (1)
--- (2)
Multiply the first equation by 2
--------- * 2
--- (3)
Subtract (1) from (3)
Solve for S
Substitute 13 for S in (2)
Solve for 4M
Solve for M
1 glass of milk and 1 snack bar = S + M
Answer:
Step-by-step explanation:
First of all, it is convenient to choose the false statement.
We note that statements 7 (Alan is first) and 10 (Alan did not finish) are contradictory, so one of them must be false. Statement 5 has Henry & Hughes together, so is not consistent with statement 7 (Alan & Hughes). So, statement 7 is inconsistent with two other statements, thus must be the false one.

The attached table shows how we parsed the statements. An "O" signifies a combination that must occur; and "X" signifies one that cannot occur. We have used "-" to fill the spaces that are inconsistent with the locations of "O". The red letters are deduced from the others.
The first complete set we found was Henry & Hughes (Don & Gladstone) who were in the (red) capsized raft and did not finish. The second complete set we found was Phil & Cook (Frank & Hawley) who were in the (yellow) raft that finished second. We know Paul & Wilson (Alan & Partner) finished last, so Phil & Cook could not have been Paul and Wilson. Finally, O'Brien and Leroy were not on the same boat, so Paul must be Paul O'Brien and Leroy must be Leroy Sands.
