Uncle Zhang sent 100 vases to a company, and the freight was 1.5 yuan. If one of them is damaged in transit, it will not be delivered.

Master Zhang sent 100 vases to a company, and the freight was 1.5 yuan. If there is any damage during transportation, the company will receive compensation of 65,438+05 yuan for each damaged vase. After delivery, Master Zhang got the freight 84 yuan. How many vases did he damage? correct

Assuming that x is damaged, then

1.5( 100-x)- 15x = 84

The solution is x=4.

Four vases were damaged.

For supplementary questions:

1.5 *( 100-x)- 15 * x = 84

Is that clear? Subtract the compensation for the damaged vase (this answer is purely plagiarism, and it is normal if there is any similarity. )
