Let 100$ be the original price. After 60% discount, the price is 40. After 30% additional the price is 40*0.7=28$. So, over all 28% of the original price will be paid

Question

Let 100$ be the original price. After 60% discount, the price is 40. After 30% additional the price is 40*0.7=28$. So, over all 28% of the original price will be paid

Answer 1

60% of $100 = .6 x 100 = $60 discount. $100-$60 = $40

30% of $40 = $12. $40-$12 = $28

the total discount off $100 was 72%

72% of $100 is $72. $100-$72 = $28 final discounted price, where you pay 28% of the original regular price

this all assumes that 30% discount is a discount off the discounted price and not a 2nd discount off the regular price. If you took 30% off $100 that's $30 off and $40-$30 would leave a final discounted price of $10 which is 10% of the original price
