Solution: Let x be the amount to be invested (15%).
Then,
x*0.15 + 550*0.11 = (x+550)*0.12
x*0.15 - x*0.12 = 550*0.12 - 550*0.11
0.03x = 550*(0.12-0.11)
0.03x = 550*0.01
0.03x = 5.5
x =5.5÷0.03
x=183.33
Answer: $183.33 more to be invested for 12 % total return.
Answer: The answer is 904.32
Let's convert one of these numbers:
1 foot = 12 inches
9 feet were 9*12=108 inches
so the ratio would be 42: 108
or we can simplify it: divide by 2:
21:54
divide by 3:
7:18
A ratio always stays the same no matter the unit or currency, so it doesn't matter which unit we convert it to.
