Broken vases |

JC pose la question :
Hello,
I need help with a question. It is said that a company delivers 1000 vases to a man. It charged $0.40 for every vase safely delivered.
But the company had to pay the man $5.10 for each broken glass.
If the man paid a total of $383.50 for the delivery, how many vases were broken?
Regs. ,
JC
