You have just passed your algebra class and you are ready to celebrate! You invite your friends over for a party. You want to make a punch and you find a recipe that calls for 4 parts of orange juice for every 5 parts of pineapple juice. You have 18 ounces of pineapple juice. How much orange juice do you need? You must set up an equation and solve.

4 / 5    =   x  /  18      where x is the ounces of orange juice


Muliply both sides by 18


(18) * 4 /5  =   72/5    =  14.4 oz  of orange juice


cool cool cool
