does this equation make sense plz help.
Thedny wants to fix his broken Xbox. he collected quotations from two different engineer. The first engineer's total cost in terms of the number of hours (x) worked was modeled as t(x) = 70 + 5x, while that of the second engineer was g(x) = 30 + 15x. Thedny knows that it will take more than 2 hours to fix his Xbox so he decided to go with the first engineer whose cost is cheaper when the number of hours is above 2 hours.
