help me please

Question

mother has provided a recipe that calls for 6 eggs for one gallon of ice cream. There will be 750 people at the party, Tangtang has bought 4-ounce paper cups how many eggs will be needed to make enough ice cream to feed everyone one serving

Answer 1

This is a perfect chance to use the factor-label method.  You have a certain number of people, and that figure needs to be converted to a number of eggs due to ounces of ice cream per person, ounces per gallon, and eggs per gallon.

 

(apologies for the formatting, Wyzant doesn't let me put things in equation format) 

 

750 persons  *  4 ounces ice cream   *    1 gallon ice cream    *         6 eggs           

                           1 person                128 ounces ice cream      1 gallon ice cream

 

You'll end up with (750 * 4 * 1 * 6) / (1 * 128 * 1)

 

The labels "person(s)," "ounce(s) ice cream," and "gallon(s) ice cream" will all cancel out, leaving you with "egg(s)."

 

Naturally, you can't buy 0.625 of an egg, so round it up to 141 eggs.
