Question

A speeding ticket costs $40 plus $5 for each mile per hour over the speed limit. Lynne mentions that she was given a ticket for $75. What is a valid conclusion using deductive reasoning?

Answer 1

Lynne was driving 7 miles per hour over the speed limit.? Correct.... @jim_thompson5910

Answer 2

good

y = cost
x = her speed (over the speed limit)

y = 5x + 40
75 = 5x+40
75-40 = 5x
35 = 5x
5x = 35
x = 35/5
x = 7

So you're correct
