Step 1
Let x be the price of one notebook. If each notebook were priced at

x - 0.30

instead, she could have bought 4 notebooks for the same price.
So,

3 x = 4 (x - 0.30) 3 x = 4 x - 1.20 x = 1.20

So she paid

$ 3.60

for three notebooks.

Step 1
Let the price of the notebook she bought be x therefore, she spends

3 \times x = 3 x

on 3 notebooks

3 x = 4 (x - 30) 3 x = 4 x - 120 x = 120 3 x = 360

She paid

$ 3.60

for 3 notebooks.
