Question

cayden has several screws on a scale, and the scale reads 80.955\,\text{g}80.955g80, point, 955, start text, g, end text. cayden adds 111 more screw, and the scale reads 84.81\,\text{g}84.81g84, point, 81, start text, g, end text. what is the mass of the last screw cayden adds?

1. The mass of the last screw Cayden adds is 3.855 g given that Cayden has several screws on a scale, and the scale reads, 80.955 g and Cayden adds one more screw, and the scale reads 84.81 g. This can be obtained by subtracting the initial mass of screws from the final mass of screws.

### What is the mass of the last screw Cayden adds?

Here in the question it is given that,
• Cayden has several screws on a scale
• Initially the scale reads 80.955 g
• Cayden adds one more screw, and the scale reads 84.81 g

We have to find the mass of the last screw Cayden adds.
Let the mass of the last screw be x.
⇒ 80.955 g + x = 84.81 g
⇒ 80.955 g + x – 80.955 g = 84.81 g – 80.955 g
⇒ x = 3.855 g
Hence the mass of the last screw Cayden adds is 3.855 g given that Cayden has several screws on a scale, and the scale reads, 80.955 g and Cayden adds one more screw, and the scale reads 84.81 g.
