Question

A pair of shoes costs $89.99. They are on sale for 30% off. The store charges a 6.5% sales tax. What is the final cost? Round to the nearest cent.

Answer 1

$76.09

Explanation:

30% off → 100% - 30% = 70%

`p\%=(p)/(100)\to70\%=(70)/(100)=0.7`

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

slaes tax = 6.5%

`6.5\%=(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
