Answer:

Quantity (lbs) of type 1 candy x = 8

Quantity (lbs) of type 2 candy y = 17,5

Step-by-step explanation:

Let´s call "x" quantity (in pounds) of candy type 1 in the mixture, and "y" quantity (in pounds ) of candy type 2, then according to the problem statement.

x + y = 25,5

2,20*x + 7,30*y = 5,70 * 25,5 ⇒ 2,20*x + 7,30*y = 145,35

Then we have a two equation system

x + y = 25,5 ⇒ y = 25,5 - x

2,20*x + 7,30*y = 145,35 ⇒ 2,20*x + 7,30* (25,5 - x ) = 145,35

2,20*x + 186,15 - 7,30*x = 145,35

5,1*x = 40,8

x = 40,8/5,1

x = 8 lbs

And y = 25,5 - 8

y = 17,5 lbs
