The answer is B. She sells each orange for $0.50 and the question is asking for the total amount of money she will make by selling a certain amount of oranges. t represents the total so the equation will to equal to t. c is the number of oranges she will sell so c multiplied by $0.50 will give the total amount of money she will make.
The answer is B. This is because "t" is what Karen will raise so that will be the total, and then she sells the oranges for 0.50 so if Karen sells "c" amount of oranges we don't actually know how many she sells so you would do c multiplied by 0.50 to get t=0.50c.
