Given:

Amount of flour in a bin = 30 cups

Flour required for each signature cake =
1(1)/(2) cups

To find:

The correct equation and graph for the given situation.

Solution:

Let F be the amount of flour in the bin and c be the number of signature cakes.

Flour required for each signature cake =
1(1)/(2) cups

Flour required for each signature cake =
1.5 cups

Flour required for c signature cakes =
1.5c cups

Amount of flour in a bin is 30 cups and it is reduced by 1.5c cups. So, the amount of flour in the bin is:


F=30-1.5c

At
c=0, we get


F=30-1.5(0)


F=30

At
F=0, we get


0=30-1.5c


1.5c=30


c=(30)/(1.5)


c=20

Therefore, the required equation is
F=30-1.5c and the 4th graph is correct.
