16a+1 is the answer to your question
C because he makes 1 1/2 liter and finishes it, which makes 0. A would be 1.50, b would be 2, and d -4
If you are doing a multi step question that looks something like this: 23+(4)-4 or longer. You will have to use a formula called BEDMAS. It stands for brackets, exponents( which are little numbers on top of a number), then you deal with division, multiplication, addition, and subtraction. You will have to solve your equation in this order. If you don’t you will get another, answer.
60x24=1440 1440x365=525600 525600x2000=1,051,200,000 about 2000 years
