Answer:
The number of watches made is 8
Step-by-step explanation:
SO the equation is C=15n+85 where C is the total cost and N is the amount of watches
1)plug in C
385=15n+85
2)move 85 to the other side so it would become -85
385=15n+85 → 385-85=15n → 100=15n
3)divide 15 from both sides
100/15=15n/15 → 25/3=n
since the number of watches can't be a fraction, we round to the lowest number which is 8(24/3)
