Answer:
One brother says of his younger brother: “Two years ago, I was three times as old as my brother was. In three years’ time, I will be twice as old as my brother.” How old are they each now?
Step-by-step explanation:
Let us suppose two years ago my brother's age was x years
Then, my age was 3x
Three years from now, my brother's age will be (x +2+3) = (x+5) years
And my age will be (3x+2+3) = (3x+5) years
But it is given that i will be twice as old as my brother.
So, 2(x+5)= (3x+5)
or, x= 5 years
So my brother's present age is 5+2= 7 years
And my age is 5*3+2= 17 years
The answer is b
explanation: she’s adding 5 to both sides
Bank 1:
$5550 for 5 years with interest 2.3% paid twice a year.
5550 x 1.023^(5 x 2) = 5550 x 1.023^10 = $6967.06 (to 2 decimal places)
(amount of money) x (multiplier - a bit like saying x (100% + 02.3%) because it's increasing the original 100% by 2.3%)^(The time the money is in the account for (years) x how many times a year interest is paid)
6967.06 -5550 = $1417.06 added during the 5 years
bank 2:
$5550 for 5 years with interest 2.2% paid 12 times a year.
5550 x 1.022^(5 x 12) = 5550 x 1.022^60 = $20480.79
20480.79 -5550 = $14930.79 added during the 5 years
comparison:
(bank 1 = + $1417.06 ) < (bank 2 = + $14930.79 )
therefore bank 2 offers the most interest.
hope this helps
