Answer:
$36
Step-by-step explanation:
- in the beginning $20 is %100 so divide 20 by 100 .
- you'll get .2 but to make this simple you'll want %10 so multiply .2 times 10 and you get 2 .
- now that 2 is %10 and you want %80 you multiply 2 8 times (or add it 8 times) because %10 times 8 = %80 so 2 times 8 = 16 .
- now that you have the %80 you want to add it to the %100 because they sold it for %80 then the price they bought if for (you get %180) .
- then you add the $20 to the $16 because that is what each percent equals (you get $36)
