Washing 2 cars and 3 trucks take 130 minutes. washing 2 cars and 5 trucks take 190 minutes. how long does it take to wash one car and one truck? show your work and explain your reasoning in the space provided below.

It takes 30 minutes for 1 truck and 20 minutes for 1 car. Therefore it will take 50 minutes to wash one car and one truck. 190-130= 60. 5 trucks -3trucks = 2 trucks. 60/2= 30 minutes per truck. Then 130- 2 trucks (60 minutes) =40. 40/2(cars)= 20 minutes per car

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5
