Plz help 3 question with explanation

Answer:
1. $79.38
2. It's correct.
Step-by-step explanation:
price: $105
discount: 30%
tax: 8%
Calculate 30% of 105 and subtract it from 105
To convert 30% to decimals, divide by 100.
[tex]\frac{30}{100}=0.30[/tex]
105-0.30(105)
105-31.50
$73.50
Now calculate 8% of it and add it.
73.50+0.08(73.50)
73.50+5.88
$79.38
