solution

 

Mia and Tia will use 2 packages of mix to make 4 pitchers of lemonade. At the end of the week the pitcher will be 1/4 filled with lemonade.

explanation

Step 1
Mia and Tia drank three quarters of a full pitcher on Monday.
1/4 pitcher + 1/4 pitcher = 3/4 pitcher
Each day of the week, they will drink the same quantity.

Step 2
In five days Mia and Tia will drink 5 x 3/4 pitcher, or 3 3/4 pitchers.
5 x 3/4 = 15/4
15/4 = 3 3/4

Step 3
The least amount of lemonade they must prepare is 4 pitchers. (3 pitchers is not enough.)

Step 4
If 1/2 package produces 1 full pitcher, then 1 package produces 2 pitchers.
To make 4 pitchers of lemonade, they need 2 packages of lemonade mix.

Step 5
They will make 4 pitchers of lemonade, but drink 3 3/4 pitchers.
To find out how much lemonade will be left:
4 – 3 3/4
At the end of the week, 1/4 pitcher of lemonade will be left.
