Answer is 30 m

$(1)/(2)$

Solution,

Letthepointsbe AandB

A(-4,1)------>(X1,y1)

B(2,4)---------->(x2,y2)

Now,

Gradient:

$(y2 - y1)/(x2 - x1)$

$(4 - 1)/(2 - ( - 4))$

$(3)/(2 + 4)$

$(3)/(6)$

$(1)/(2)$

Micah deposited $4000 between two savings account. One account earns 4% simple interest each year. The other account earns 2% simple interest. Last year Micah earned $140 interest on the accounts. What amount was originally deposited into the account that pays 4% interest?

Answers

Answer:

The amount that is deposited at 4 % simple interest is $ 3000.

Step-by-step explanation:

Given, the total amount deposited = $ 4000,

Let x be the amount that is deposited at the rate of 4 % simple interest,

⇒ The amount deposited at the rate of 2% simple interest = ( 4000 - x ) dollars,

We know that,

The simple interest on an amount is,

$I=(P* r* t)/(100)$

Where, P is the principal amount, r is rate of interest and t is time,

Thus, the total interest he earned in a year

$I=(x* 4* 1)/(100)+((4000-x)* 2* 1)/(100)$

$=(4x)/(100)+(2(4000-x))/(100)$

$=(4x+2(4000-x))/(100)$

According to the question,

I = $ 140,

$\implies (4x+2(4000-x))/(100)=140$

$(2x+8000)/(100)=140$

$2x+8000=14000$

$2x=6000$

$x=3000$

Hence, the amount that is deposited at 4 % simple interest is $ 3000.

$3000 * 0.04 = $120
$100 * 0.02 = $20

total 2 accounts = $120 + $20 = $140

answer: $3000 was the originally deposited into the account that pays 4% interest.
