Let X represent the cost of 1 pear and Y represent the cost of 1 peach.
Use the given information to set up a system of equations:
5X + 6Y = 11.20
3X = 2Y
Use the second equation to solve for Y:
3X = 2Y
Y = 1.5X
Plug the new found value for Y into the first, unused equation:
5X + 6(1.5X) = 11.20
Simplify:
5X + 9X = 11.20
or
14X = 11.20
Solve for X:
X = .8
Now that you have the value for X, you can plug it into either of the first two equations to solve for Y:
3X = 2Y
3(.8) = 2Y
2.4 = 2Y
Y = 1.2
Each pear is $0.80 and each peach is $1.20.

Answer:
Step-by-step explanation:
p = Penny's salary
Karen's salary = $580 more than half of p
We can use the fraction to represent half of p.
Since Karen's salary is $580 more, her salary is $580 + .
