If $6,000 is invested for six years and seven months at 6% compounded semi-annually, what is the interest that the investment earns?
select one: a. $2,832.45 b. $2,854.72 c. $2,814.78 d. $2,833.96

Option (B) is correct.

Given:

P = $6000

r = 6%

t = 6 years and 7 months = 79 months

∵ It is compounded semi-annually

∴

I = 8854.72 - 6000

I = 2854.72

step-by-step explanation:

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
