How many minutes would it take for the cost of repair to reach $60 Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! Hi there,
y=47.38 + 0.617x
47.38 + 0.617x = 60
0.617x = 60 - 47.38
0.617x = 12.62
x = 12.62/0.617
x = 20.45 minutes (2 decimal places)
Hope this helps :-)
