Question

Diego is baking cookies for a fundraiser. He opens a 5-pound bag of flour and uses 1.5 pounds of flour to bake the cookies. Which equation or inequality represents f, the amount of flour left in the bag after Diego bakes the cookies?

a) f = 1.5
b) f > 1.5
c) f = 3.5
d) f > 3.5

Answer 1

After using 1.5 pounds of a 5-pound bag of flour, the amount left is calculated by subtracting the used amount from the initial amount, resulting in 3.5 pounds. The correct answer is c) f = 3.5.

Step-by-step explanation:

The question asks to determine the amount of flour left in the bag after Diego has used some of it for baking cookies. Starting with a 5-pound bag of flour, if Diego uses 1.5 pounds of flour, the amount of flour left, denoted as f, can be found by subtracting the used amount from the starting amount. Therefore, the equation representing f, the amount of flour left in the bag, is:

f = 5 - 1.5

When solved, this equation gives:

f = 3.5

Therefore, the correct answer is c) f = 3.5.
