A16 oz bottle of juice costs $2.00. what is the unit cost a-$0.075/fl. oz
b-$0.125/fl. oz
c-$0.36/fl. oz
d-$0.40/fl. oz

The answer is B-$0.125/fl.oz

Step-by-step explanation:

$2.00/16 = $0.125/1

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:
