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

Answer:

$76.09

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
