To warm up the machine takes 28.5 minutes.
Once warmed up, the machine can produce a toy in 9.25 minutes.
To find the total time to produce 78 toys, we add the time to warm up with the time to produce the toys:
28.5 + (78 * 9.25) = 28.5 + 721.5 = 750 minutes.
To convert minutes to hours, we divide by 60:
750 / 60 = 12.5 hours.
Therefore, the machine will take 12.5 hours to produce 78 toys.
