Answer:
<em>He should pack </em><em>9 loaves</em><em> of bread for a 12 day hiking trip if he eats the same amount of bread each day.</em>
Step-by-step explanation:
Hint- This can be solved by Unitary method.
Sam used 6 loaves of elf bread on an 8 day hiking trip.
or in an 8 days trip he used 6 loaves of bread,
so in 1 day he would use loaves of bread,
so in a trip of 12 days he would use loaves of bread.
Therefore, he should pack 9 loaves of bread for a 12 day hiking trip if he eats the same amount of bread each day.
