Answer 1

Correct question:

Cayden has several screws on a scale, and the scale reads 80.955 g. Cayden adds 1 more screw, and the scale reads 84.81 g. What is the mass of the last screw Cayden adds?

Answer:

The mass of the last screw Cayden adds is 3.855 g.

Step-by-step explanation:

From question, weight of the screws in the scale = 80.955 g

From question, weight of the screws after adding in the scale = 84.81 g

Now, the weight of the last screw is given as:

Wt of last screw = Wt after adding screw - Wt of the screws initially

On substituting the values, we get,

Wt of last screw = 84.81 - 80.955

∴ Weight of the last screw = 3.855 g
