Answer:
The amount in the first account is $5,700
The amount in the second account is $1,300
Step-by-step explanation:
Let the mount invested in the first account be and the one invested in the second account be
.
Then the total principal is ---->(1)
The interest in the first account is
The interest in the first account is
The total interest for the year is 262.00.
This implies that:
---->(2)
We solve the two equations simultaneously to get:
and
This function starts at , so we have
.
Then, every time increments by 1,
doubles. This is typical of exponential functions. In linear functions, every time
increments by 1,
increments by a fixed amount (the slope of the function).
So, this is an exponential function, and the equation is
Answer:
let required no be x
by doing crisscrossed multiplication
42=7x
dividing both side by 7
6=x
therefore x=6
therefore value of remaining no.is 6
