Question 277416
Books and magazines.  At Gwen’s garage sale, all books were one price, and all magazines were another price.  Harriet bought four books and three magazines for $1.45, and June bought two books and five magazines for $1.25.  What was the price of a book and what was the price of a magazine.

(I need to see how you came up with your answer please)


let the cost of the books be x
And the cost of the magazoines be y

Harriet------------  4x+3y= 1.45-------- 1
JUne-----------------2x+5y=1.25----------2

Multiply eq 2 by 2

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

subtract eq. 3 from eq 1

-7y= 1.45-2.5
-7y= -1.05
y= -1.05/-7

y= 0.15 or 15 cents

2x+5y= 1.25

2x+5*0.15 = 1.25

2x= 1.25-0.75

2x= 0.5
x=0.5/2
x= 0.25 or 25 cents
