OK so first I like to find what 10% is which in this case would be 1.8 and to find the other 5% you divide 1.8 by 2 which gets you .9 if you and 1.8 and .9 you get 2.7 and if you add 2.7 to 18 you get 20.7 which is your retail price
15/100 × 215 = 3225/100
= 32.25

Answer:
you can simplify rations just like you simplify fractions. Whenever you are able to evenly divide both parts of the ratio with out changing the equation's answer, you are able to.
for example
if it were 3:6, you can simplify this by dividing these both by 3, leaving you with 1:2.
1000*200=200000
This will be your answer
thanks
