The candy store owner should use 37.5 pounds of the candy costing $1.25 a pound.
Given:
- Candy costing $1.25 a pound is to be mixed with candy costing $1.45 a pound
- The resulting mixture should be 50 pounds of candy
- The resulting mixture should cost $1.30 a pound
To find: The amount of candy costing $1.25 a pound that should be mixed
Let us assume that the resulting mixture should be made by mixing 'x' pounds of candy costing $1.25 a pound.
Since the total weight of the resulting mixture should be 50 pounds, 'x' pounds of candy costing $1.25 a pound should be mixed with '' pounds of candy costing $1.45 a pound.
Then, the resulting mixture contains 'x' pounds of candy costing $1.25 a pound and '' pounds of candy costing $1.45 a pound.
Accordingly, the total cost of the resulting mixture is
However, the resulting mixture should be 50 pounds and should cost $1.30 a pound. Accordingly, the total cost of the resulting mixture is
Equating the total cost of the resulting mixture obtained in two ways, we get,
This implies that the resulting mixture should be made by mixing 37.5 pounds of candy costing $1.25 a pound.

Answer:
<u>1 cup</u> of milk Juan should use.
Step-by-step explanation:
Given:
A recipe calls for 120 ml of milk for each 200 g of flour.
Juan is going to use 1 pound of flour.
Now, to estimate the number of cups of milk.
Let the quantity of milk be
Now, to convert the pound of flour to gram.
1 pound = 453.59 g.
So, Juan is going to use 453.59 g of flour.
As, given recipe calls for 120 ml of milk for each 200 g of flour.
So, 120 ml is equivalent to 200 g.
Thus, is equivalent to 453.59 g.
Now, to solve by using cross multiplication method:
By cross multiplying we get:
Dividing both sides by 200 we get:
The quantity of milk = 272.154 ml.
Now, converting the quantity into cups by conversion factor:
1 ml = 0.004 cup.
So, 272.154 ml of milk is:
272.154 × 0.004
=1.088 cups.
Estimating the number = 1 cup.
Therefore, 1 cup of milk Juan should use.
