You bought an investment for $1000 and 5 years later sold that investment for $1700. taking into account compounding, what was your average annual return during the investment? round your answer to the nearest tenth of a percent and use decimals

11.19%

Step-by-step explanation:

We will use compound interest formula :

A = accumulated value = $1,700

P = principal amount   = $1,00

r  = rate of interest = ?

n  = number of compounding = 1

t   = time = 5 years

Now put the values into formula

1.7 = (1+r)⁵

1.1119 = 1 + r

r = 1.1119 - 1

r = 0.1119

R = 0.1119 × 100

  = 11.19%

Average annual return was 11.19%  

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:
