$\\ \sf\longmapsto f(-3)$

$\\ \sf\longmapsto -(-3)^2=-9$

$\\ \sf\longmapsto f(-5)$

$\\ \sf\longmapsto 5(-5)-2=-25-2=-27$

$\\ \sf\longmapsto f(-6)=5(-6)-2=-30-2=-32$

Yesterday's price of notebook = $3.45

Today's price of notebook = $3.20

We have to determine the percentage decrease in the cost of notebook.

Percentage decrease = (Decrease $\div$ Old price) $\times 100$

So, percentage decrease = $\frac{3.45-3.20}{3.45} \times 100$

= $\frac{0.25}{3.45} \times 100$

= 7.246%

= 7.25%

Therefore, there is 7.25% of decrease in the cost of the notebook.
