Hey there!
The answer to your question is $58.24
First, we will find the clearance price by finding 70% of the original price, since 30% was taken off:
0.70 x 104
72.80
Then, we will find the price after the coupon by finding 80% off 72.80, since 20% was taken off:
0.80 x 72.80
58.24
Hope it helps! Have a great day!
