I need help with these 3 more than half a number is less than 20
2 times less than 16 is at least 50
100 is less than a number divided by 2.83

I just need them translated into numbers I can find the answer from there

Step-by-step explanation:

n/2 + 3 < 20

50 >= 16- 2n

n / 2.83 > 100

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:
