Brian has 40000 to invest in a mix of corporate and municipal bonds. The corporate bond pays 10% simple annual interest and the municipal bonds pays 6% simple annual interest. If he expects to receive 3600 in interest payments this year, how much has Brian invested in the corporate bond?

Sum of money invested in corporate bonds = 30,000

Step-by-step explanation:

Total sum = 40,000

The rate of interest for corporate bonds = 10 % = 0.1

The rate of interest for municipal bonds = 6 % = 0.06

Total interest = 3600

Let sum of money invested in corporate bonds = x

The sum of money invested in municipal bonds = 40000 - x

× 0.1 × 1 + () × 0.06 × 1 = 3600

(0.1- 0.06) + 2400 = 3600

0.04 = 1200

= 30,000

Since x =  sum of money invested in corporate bonds

So  sum of money invested in corporate bonds = 30000

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
