Pending Review Question 7

vitfil [10]

Answer:

$ 2,200 for 8%, $ 1,300 for 12%

Step-by-step explanation:

I=PRT

Let Bank 1 be <em>x</em>

332= x (8%) + (3,500-x) 12%

332= x (0.08) + (3,500-x) 0.12 change the percent to decimal

332= 0.08x + 420 - 0.12x

0.04x= 420-332

x= $\frac{88}{0.04}$

x= 2,200 (Bank 1)

Bank 2= 3,500-Bank 1

Bank 2= 3,500- 2,200

Bank 2= 1,300
