Betsy, a recent retiree, requires $6000 per year in extra income. she has $50,000 to invest and can invest in b-rated bonds paying 13% per year or in a certificate of deposit (cd) paying 5% per year. how much money should be invested in each to realize exactly $6,000 in interest per year?

Total funds available with Betsy = $50,000

Interest rate in B-rated bonds = 13% per year

Let amount invested in B-rated bonds be x

Interest rate in certificate of deposit (CD) = 5% per year

Amount invested in CD = 50,000-x

Now, we have to determine x such that Betsy can get exactly $6,000 in interest per year. Hence:

x * 13% + (50,000 - x) * 5% = 6,000

⇒ 0.13x - 0.05x + 2,500 = 6,000

⇒ 0.08x = 3,500

⇒ x = 43,750

Hence, Betsy should invest $43,750 in B-rates bonds

And 50,000 - x = 50,000 - 43,750 = 6,250

And she should invest 6,250 in CD

step-by-step explanation:

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
