Dan learned the mass of an electron is about 9.1×10⁻³¹ while the mass of a proton is about 1.7×10⁻²⁷. He thinks electrons have a greater mass than protons because 9.1 is greater than 1.7; Do you agree with him? How can you use scientific notation to compare the mass of an electron and a proton? Explain your thinking.

answer: $420.00

step-by-step explanation:   multiply $400.00 by 5%.

400.00*.05=20

400+20 = 420
