Answer:

To determine how many pounds of each type of candy you bought, let's set up a system of equations based on the given information.

Let's assume you bought x pounds of Candy A and y pounds of Candy B.

According to the given information, the cost of Candy A is $4.20 per pound, so the cost of x pounds of Candy A would be 4.20x dollars.

Similarly, the cost of Candy B is $5.65 per pound, so the cost of y pounds of Candy B would be 5.65y dollars.

Since the total cost of the candy is $64.60, we can set up the equation:

4.20x + 5.65y = 64.60

Additionally, we know that the total weight of candy purchased is 14 pounds, so we have the equation:

x + y = 14

Now we have a system of two equations:

4.20x + 5.65y = 64.60

x + y = 14

To solve this system, we can use substitution or elimination methods.

Let's use the elimination method. Multiply the second equation by 4.20 to eliminate the x term:

4.20(x + y) = 4.20(14)

4.20x + 4.20y = 58.80

Now we have the following system of equations:

4.20x + 5.65y = 64.60

4.20x + 4.20y = 58.80

Subtract the second equation from the first equation:

(4.20x + 5.65y) - (4.20x + 4.20y) = 64.60 - 58.80

1.45y = 5.80

Divide both sides by 1.45 to solve for y:

y = 5.80 / 1.45

y = 4

Substitute the value of y back into the second equation to solve for x:

x + 4 = 14

x = 14 - 4

x = 10

Therefore, you bought 10 pounds of Candy A and 4 pounds of Candy B to stay within your budget of $64.60 and purchase a total of 14 pounds of candy.
