Marie and Lori are starting a business to make gourmet toffee. They gather the following information from another business about prices for different amounts of toffee. Which equations and which graph are most likely to model the price for ,p, for x amount of toffee? justify your answer.
Equation A- p=5x+2.2
Equation B- p=7.2 square root of x
This question can't be answered exactly because no figure was given. However, I could still help you because the concept here is clear. We can tell from the choices that Equation A is a line and Equation B is half of a parabola. Equation A is a line because it has a general form of ax+by = c. Equation B is half a parabola, because a parabola contains either a x² or y² term.
With that being said, if the graph in this problem shows a straight line, then the answer is Equation A. If the graph in this problem shows a curve that resembles one half of a parabola, then the answer is Equation B.
