ir the final cost is the wholesale pluss 15%. it is 115% because the wholesale would 100%.
so we have: 545,10=115%
and 100%=x where x is the wholesale cost
we get:
545,10=115%
x=100%
multiplying inverse:
115*x=545,10*100
115x=54510 --> we pass the 115 dividing
x=54510/115
x=474
The cost wholesale is $474,00
