Answer:
5 : 1
Step-by-step explanation:
From your second-grade memorization of multiplication tables, you recognize that 15 = 3×5, so you know 3 is a factor of both numbers in the ratio. To reduce the ratio to simplest form, you divide out all common factors:

Step-by-step explanation:
Let the number be x.
x - 3 = 10x
9x = -3
x = 
Your total price would be 159 because when you multiply the 150 by 6% you get 9 then add that to your 150 which is 159.
