Rachel earns $150 per month from her job at the local library plus $6.00 per hour from babysitting jobs. if she wants to earn at least $300 this month, how many hours will she need to babysit?

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:

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6
