A bank loaned out $20,000, part of it at the rate of 9% per year and the rest at 17% per

Black_prince [1.1K]

Answer:

The bank loan out at $5000 at 9%

Step-by-step explanation:

A bank loaned out $20,000

Let x be the amount loaned at at the rate of 9% per year

So, 20000-x amount loaned at at the rate of 17% per year

Formula : $A =P(1+r)^t$

Amount at 9% interest in 1 year

$A=x(1+0.09)^1$

A=1.09x

Interest = Amount - Principal = 1.09x-x=0.09x

Amount at 17% interest in 1 year

$A=(20000-x)(1+0.17)^1$

A=1.17(20000-x)

Interest = Amount - Principal = 1.17(20000-x)-(20000-x)

We are given that the interest received in one year totaled $3000

So,1.17(20000-x)-(20000-x)+0.09x=3000

x=5000

So, the bank loan out at $5000 at 9%
