The ratio of isabella's and shane's ratio is 3 to 11.if isabella has 33 dollars ,how much money do shane and isabella have put together?

this problem requiers proportion.

Answer 1

Isabella:Shane = 3:11 = 33:X 

 

3/11 = 33/X

 

Therefore X = 33 * 11 /3 = $121

 

Total = 121 + 33 = $154

 

Alternatively; Let Y be the total amount

 

3/(3+11) = 33/Y

 

Y = 14 * 33/3 = $154

Answer 2

Isabella : Shane :: I : 33

3 : 11 :: I : 33

Isabella has $11
