Eric made two investments:

•Investment Q\text{Q}Qstart text, Q, end text has a value of $500\$500$500dollar sign, 500 at the end of the first year and increases by $45\$45$45dollar sign, 45 per year.
•Investment R\text{R}Rstart text, R, end text has a value of $400\$400$400dollar sign, 400 at the end of the first year and increases by 10%10\%10%10, percent per year.

Eric checks the value of his investments once a year, at the end of the year.

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:
