JamesTDG · Answer

You could resolve this simply by substituting c with 83 and t with x, afterwards, input it into a graphing calculator, where the line crosses the x-axis is your answer

That is, if you are allowed to use graphic calculators such as Desmos

Your answer is: t = 3

83 = 24.5t

73.5 = 24.5t

t = 3

t = tickets

b = 2

m = -2/5
