I set it up like this. (.30)(x) + .10(100-x) = .12( 100) and solved for x. x = 10 gallons... therefore 10 gallons of 30% and 90 gallons of 10% Less

What skills and experiences do you have that will help you be successful in this role?

I have good communication skills - I can explain concepts with appropriate details, depending on my audience. I frequently ask my audience if they understand what I'm saying, and if not, I try to explain in other ways. As for experience, a group of friends and I made a study group during our first year in university. I was in charge of clarifying any confusions that arose in math classes. I have helped a lot of my friends with various problems in assignments and past exams. After I explained to them a certain concept that the question was asking to apply, they were able to easily solve said problems. Less
