3. Use the formula A=P (1+r/n)^nt to find the amount of money you would have after 20 years if you invested $5,000 at 5% compounded quarterly. 4. You invest $2,000 at 8% interest compounded quarterly 40 years before you retire. How much money would you have when you retire? 5. You have $10,000 to put into savings.

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:
