-16+4n
Just have to simplify
Answer: You meant a picture?
Step-by-step explanation: The model is here:
Y=x+70
Slope-intercept form
THE 5 IDENTICAL SHELVES WOULD have to be 76 because if you take 400 - 20 (because that left over) you get 380/5 you get 76 and to check your work you do 5x76=380+20 you get 400 so 76 is you answer
Written just as an expression it would be:
15-5(p-6)
