Ross bought classic comic books for 10 each. when the price increased to $17 per book, he sold all of his comic books except one. his profit was $49. how many comic books did ross buy? explain how you found the answer.

x = number of comics Ross bought

A = 10*x = amount spent on buying those x number of comics at $10 each

B = 17*(x-1) = amount Ross gets from selling every comic book except one

B-A = 17*(x-1)-10x = 7x-17 = profit = 49

7x-17 = 49

7x = 49+17

7x = 66

x = 66/7

x = 9.42857 approximately

Because x isn't a whole number, I'm thinking that there's a typo in the problem somewhere. I would double check with your teacher.

step-by-step explanation:

negitive slope

d) 30 units^2

area of rectangle = l × b
