Help please just this I will mark someone's answer the brainliest if they answer correctly. 3. A library charges a late fee of $3.50 plus $0.15 per day that a book is returned late. B. Make an equation to find if the total fee if a book is 10,15,20, or 25 days late. Then graph the ordered pairs.

a. f = 3.50 + 0.15d

b. please see the analysis

Explanation and graph given in the picture

I hope it helps.

The coordinates of point a right now is (-3,-1) you have to multiply these coordinates by a factor of 2 to get (-6,-2)

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
