Answer:
As you can see, these are all set up in slope intercept form (with a y-intercept of 0). These equations are called "direct variation" because y varies directly with x. If x increases, then y increases as well. If x decreases, then y decreases.

there are 5280 feet in a mile so 5280 times 3 is 15,840.
3 cups= 15 people
60/15= 4
4*3=12
Lenny needs 12 cups of sauce
If your solving for x, then the new equation is
If your solving for y, then the new equation is
To find the sale price now you can divide x by 5 and then multiply that by 4
