<u>Complete Question:</u>
<em>Ben is 4 times as old as Ishaan. 6 years ago, Ben was 6 times as old as Ishaan. How old is Ishaan now?</em>
<em />
Let Ben's age be "b" and Ishaan's age be "i"
Since Ben is 4 times as Ishaan, we can write:
b = 4i
Ben was 6 times as Ishaan, BUT 6 years ago, we setup the equation like shown below:
b - 6 = 6(i - 6)
Multiplying, we have:
Now, we replace b with "4i" and solve for i (Ishaan's age now):
Ishaan is now 15 years old
Answer:
The amount invested at 4% is $20,500 and the amount invested at 10% is $500
Step-by-step explanation:
Let
x -----> the amount invested at 4%
(21,000 -x) ----> the amount invested at 10%
we know that
The interest of the amount invested at 4% plus the interest of the amount invested at 10% must be equal to $870
so
Solve for x
therefore
The amount invested at 4% is $20,500 and the amount invested at 10% is $500
