The store is having a sale wear winter clothes are 60% of the original price a sweater is on sale for $30 what was the original price of the sweater

This might not help but this is how you would work the problem if it was the other way around. The original price of a shirt is $100 now the shirt it 30% off so you multiply 100 and .30 which gets you $30. Then you subtract $100 from $30 which gets you $70 which is now your cost on sale. which now you have to find 50% off your sale price($70) which would become $35 after you multiply 50% and $70 then you would subtract $70 from $35 which gets you your final cost. I'm sorry if this didn't help you at all
