Stephanie adds pennies, nickels, and quarters to a scale until the mass of
the combined coins is 75 grams. Each penny has a mass of 2.5 grams, each
nickel has a mass of 5 grams and each quarter has a mass of 5.7 grams.
Create an equation to model this situation, where x is the number of
pennies, y is the number of nickels, and z is the number of quarters that
Stephanie can put on the scale so that the combined mass is exactly 75
grams. *
