A food truck sells cold subs and hot cheesesteaks. The truck has never sold more than a total of 125 subs and cheesesteaks in one day. It always sells at least 60 cold subs but never more than 80. It always sells at least 40
hot cheesesteaks but never more than 60. If the food truck makes a profit of $0.75 on each cold sub and Sl on
each hot cheesesteak, how many of each item would maximize the food truck's daily profit? LABEL THE
SCALES ON BOTH AXES

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
