Answer: $91
Explanation: to know what is the sale price, we need to calculate the 30% of $130 and then substract it from that initial price:
To calculate the 30% of 130 we multiply 130 by 30 and divided by 100:
discount=30*30/100
discount=$39
Now we calculate the sell price:
sell price= initial price-discount
sell price=$130-$39
sell price=$91
