While on a walk in the country, you pass a field full of horses and chickens. After a quick count, you determine there are 43 he

Irina-Kira [14]

Horse = x = 1 head and 4 feet

Chicken =y = 1 head and 2 feet

Horse + chicken = x + y = 43 ( total heads)

Horse = 43 - y

4x + 2y = 122

4(43-y) + 2y = 122

Simplify:

172-4y + 2y = 122

Combine like terms

172-2y = 122

Subtract 172 from both sides

-2y = -50

Divide both sides by-2

Y = 25

X + y = 43

X + 25 = 43

X = 18

There are 18 horses and 25 chickens.

Rachel invested $15,000 in a nine-year CD giving 8.5% interest, but needed to withdraw $4,000 after two years. If the CD's penal

drek231 [11]

Given:
Principal = 15,000
interest = 8.5%
term = 9 years

I = 15,000 * 8.5% * 9 years = 11,475
total amount after 9 years = 15,000 + 11,475 = 26, 475

Preterm after 2 years. wdl of 4,000. penalty is 6 months interest of 4,000

I = 4,000 * 8.5% * 6/12 = 170 amount of penalty
I = 15,000 * 8.5% * 2 years = 2,550 interest earned for 2 years

15,000 + 2,550 = 17,550
17,550 - 4,000 - 170 = 13,380 amount to be invested for another 7 years

I = 13,380 * 8.5% * 7 years = 7,961.10
total amount after 9 years with pretermination
13,380 + 7,961.10 = 21,341.10
