Ryan has a total of $80
It costs $5 and $1.25 for every minute on the trampoline floor
If the total cost = y and every minute is x
The required equation hence is
$y = $5 + $1.25x
Since, he has $80 in his wallet y = $80
1) $80 = $5 + $1.25x----------- required equation
2) we solve the equation thus
80 = 5 + 1.25x
80-5 = 1.25x
75 = 1.25x
75/1.25 = 1.25x/1.25
x =60 minutes
3) The solution represents the fact that it will cost Mr. Ryan 60 minutes to exhaust his $80 at Launch Trampoline center
