Ineed asap mrs. hool is planning on grading tests over the weekend. the number of tests that she has left to grade after each hour can be modeled by the equation = 78 − 15ℎ, where is the number of tests left to grade and ℎ is the number of hours she has worked on grading. what is the meaning of the values 78 and −15 in this equation?

-15 is how many tests per hour i think, and 78 is how many tests total

Step-by-step explanation:

= 78 − 15ℎ

1 hour would be

78-(15x1)=63

2 hours would be

78-(15x2)=48

and so on.

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

215.92 dollars is the answer
