(A)
4x+3y=14.50
5x+6y=21.50

4x=14.50-3y

X=3.625-0.75y

18.125-3.75y+6y=21.50

2.25y=3.375

Y=1.5

X=3.625-0.75(1.5)

X= 2.5 , Y = 1.5

Notebook = 2.5
Pen=1.5



Part (B)

Part (B)

1 pen =3 notebooks

With the statement for each pen he buys he buys a notebook that means he spends $9 per purchase on both so for $27 dollars he would get 3 pens
