do you just want the answers or do you want to know how to take their?
120 X 0.40 (40%) = 48
120 - 48=72
The new price is $72
I don't know how to work out the other one. I'm sorry!
a) $120 multiplied by 0.6 gives you 60% of $120, i.e. the price of the book after it has been reduced by 40%.
b) $24 divided by 60 afterwards multiplied by 100 gives you the original full price. $24 represents 60% of the original price (full price minus 40% discount). Dividing $24 by 60 (%) give you 1% of the original price. Multiplying 1% by 100 gives you 100% or the original price of the book until that time it was reduced.
