A moving company charges $800 plus $16 per hour. Another moving company charges $720 plus $21 per hour. How kind is a job that costs the same no matter which company is used?

Relax

Respuesta :

 800 + 16h = 720 + 21h 
80 = 5h 
h = 16 hr 

1200 + 100d = 3230 – 190d 
290d = 2030 
d = 7 days 

2500 + 150m = 3000 + 125m 
25m = 500 
m = 20 months
