Calculate the simple interest earned on an investment of $1560 at 3% per year for 5 years. Give the answer to the nearest cent.

9514 1404 393

  $234.00

Step-by-step explanation:

Simple interest is computed using the formula ...

  I = Prt

when principal P is invested at annual rate r for t years.

  i = $1560×0.03×5 = $234.00

The interest earned is $234.00.

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:

14

step-by-step explanation:

14 x 3 = 42
