Answer:
Step-by-step explanation:
If he earns $2 per hot dog sold, then the algebraic expression for this is 2x, where x is the number of hot dogs sold. If he has to put out $48 to buy the supplies, that is represented as -48. The function, then, that represents the profit earned by selling the hot dogs is
y = 2x - 48
If you keep the radius the same and double the height, you find that by experimentation with this a few times, doubles your volume as well. That means that instead of 1/3 pi r^2 h, we will have 2/3 pi r^2 h. Your answer B.
