AAA Company currently sells radios for $ 80 less 25 % . Their competitors are now selling the same product for $ 48 . AAA must offer an additional discount of _____ in order to meet their competitor's price. A single discount of _____ will give the same net price.
(a) 10.00 % ; 60.00 % (b) 20.00 % ; 40.00 %
(c) 10.00 % ; 40.00 % (d) 20.00 % ; 60.00 %
I am not asking for the answer i just need help to figure out how to get to the answer like is there some sort of formula to figure it out or what strategy can i use to figure it out please help me.

addition discount x %
.75(80)(1x) = 48
60  60x = 48
60x = 12
x = 12/60 = .20
They have to offer another 2%
check: (.75)(.8)(80) =48
