Answer:

<h2>$76.09</h2>

Step-by-step explanation:

30% off → 100% - 30% = 70%

p\%=\dfrac{p}{100}\to70\%=\dfrac{70}{100}=0.7

70% of $89.99 → 0.7 · $89.99 = $62.993

slaes tax = 6.5%

6.5\%=\dfrac{6.5}{100}=0.065

6.5% of $62.993 → 0.065 · $62.993 = $4.094545

The final cost:

$62.993 + $4.094545 = $76.087545 ≈ $76.09
