Question 146119
Let x the price of the books and
    y the price of the magazines

  Harriet bought 4 books and 3 magazines for $1.45
then 4x+3y=1.45

 June bought 2 books and 5 magazines for $1.25
then 2x+5y=1.25

system is:
4x+3y=1.45
2x+5y=1.25 (-2)

4x+3y=1.45
-4x-10y=-2.5

adding bot equations:

-7y=-1.05

y = 0.15 

using first eq
4x+3(0.15)=1.45
4x=1
x=0.25

Solution:

The price of a book is 0.25

The price of a magazine is 0.15
