Tems11 [23]

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 \dfrac{6}{8} loaves of bread,

so in a trip of 12 days he would use \dfrac{6}{8}\times 12=9 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.

Evan and Carter are making chocolate milk which mixes milk with chocolate syrup. Evan's recipe calls for 5 cups of milk for ever
Alex73 [517]

Answer:

Evan's recipe

Step-by-step explanation:

Given that:

Evan's recipe :

5 cups of milk for every 4 teaspoons of chocolate syrup

Carter's recipe:

3 cups of milk for every 2 teaspoons of chocolate syrup.

Recipe with the stronger tasting chocolate milk:

Take the ratio of cups of milk to teaspoons of chocolate syrup:

Evan's :

5 / 4 = 1.25

Carter's :

3 /2 = 1.5

Evan's recipe has the stronger tasting chocolate milk recipe :

5 milk cup = 4 chocolate spoons

Number of chocolate milks for 3 milk cups = x in Evan's recipe

5 = 4

3 = x

5x = 12

x = 12/5

x = 2.4 teaspoons

This is 2.4 spoons compared Carter's recipe which uses 2 spoons for every 3 milk cups
