Answer:
405
Step-by-step explanation:
445.50/1.10= 405 is the answer
Answer:
cost including tax = $445.5
rate of tax= 10%
cost excluding tax= x(say)
Now,
cost including tax = x + 10% of x
or, 445.5 = x + (10x)/100
or, 445.5 = (10x + x)/10
or, 445.5*10 = 11x
or, 4455/11 =x
or, x = 405
Hence, cost of the watch before tax is $405.
