Answer:
A. $350.46
Explanation:
Step1: Calculate price after 30% discount
$620\times(1 - 0.3)=620\times0.7 = 434$
Step2: Calculate price after 15% discount
$434\times(1 - 0.15)=434\times0.85 = 368.9$
Step3: Calculate price after 5% discount
$368.9\times(1 - 0.05)=368.9\times0.95=350.455\approx350.46$
