Question 645795:
Your grandmother made 360 oz of jelly. She
had two types of jars, holding 10 oz and 12 oz,
respectively.
Let x =number of 10-oz jars and
y =number of 12-oz jars.
Write an equation that represents the dif-
ferent numbers of 10-oz jars and 12-oz jars
that will just hold all of the jelly.
1. 10x + 10y = 360
2. 10x + 12y = 10(360)
3. None of these
4. 10x + 12y = 360
5. x + y = 360
6. 12x + 10y = 360
