What is the total pressure in the reaction flask at the end of the reaction?

Question:

PLEASE,, I want to know HOW to do it. not just the answers. Explanations would be absolutely wonderful! Thank You
Consider the following reaction in a closed reaction flask. If 1.50 atm of gas A is allowed to react with 0.500 atm of gas B and the reaction goes to completion atconstant temperature and volume, what is the total pressure in the reaction flask at the end of the reaction? What are the partial pressures of the gases in theflask?
6A(g) + 2B(g) ? 2A3B(g)
A-(0.250 atm of A3B produced) + (0.500 atm of A remaining) = 0.750 atm total pressure
B-0.500 atm of A3B is produced, and since no other gases remain, 0.500 atm is the total pressure
C-(0.500 atm of A3B produced) + (1.00 atm of A remaining) = 1.50 atm total pressure
D-(0.500 atm of A3B produced) + (0.500 atm of A remaining) = 1.00 atm total pressure
