A baker has a bin filled with 30 cups of flour. His signature cake requires one and a half cups of flour. Determine which graph and which equation represent the amount of flour in the bin, F, after he bakes c signature cakes.

Respuesta :

The first thing we are going to do in this case is define variables:
 F = the amount of flour in the bin
 c = signature cakes
 We write the equation that best fits the problem which will be given by:
 F = -1.5c + 30
 Answer: 
 An equation that represents the amount of flour in the bin, F, after he bakes c signature cakes is: 
 F = -1.5c + 30 
 See attached graph.
