Given
Vanessa has a total of $8.
She spends $6 to buy poster boards
She spends the rest to buy some pens
Each pen costs $0.30.
If the number of pens that can be bought is represented by x
Then,
The total amount spent on pen is 0.3x
The total amount spent on postal boards is $6
Total money available is $8
Therefore, 0.3x + 6 ≤ 8
0.3x ≤ 8 – 6
0.3x ≤ 2
