Your friend asks you to bring ice cream to his party. there are several brands of ice cream, each with a different size and price. write a formula that will you find the price per gram for each brand. let's let x = price of carton of ice-cream y = number of grams in carton z = price per gram

The formula that will help in find the price per gram for each brand is given by

Step-by-step explanation:

Let x be the price of carton of ice cream

Let y be the number of grams in carton

Let z be the price per gram.

Since we know that

Price per gram × Number of grams in carton = Price of carton of ice cream

So, the formula that will help in find the price per gram for each brand is given by

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:
