Aden wants to sell his old baseball cards. The original price of each baseball card was $3. He wants to markup the price by 25%. For what price is Aden selling each baseball card?

3.75

Step-by-step explanation:

half of 3 is 1.5 and half of 1.5 or a quarter of 3 is .75

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:
