Question 1175073
One way is to do it all by percentages and convert at the end.
Starts with price of x
loses 18%, so 0.82x
then loses 8% of that or 6.56%, so now 75.44%x left
Then loses 60% more or 75.44*0.60=45.264% lost or 30.176% left
multiply that by the original price and get $135.79.

A second way or a check is
$450*0.18=$81 discount, so now selling for $369
mark down 8% and that is $29.52 less, so selling price is now $339.48
Now mark that down 60% and discount is $203.688 or $203.69
Subtract that from $339.48 and get $135.79
