Respuesta :

Number of golfers that didn't qualify = 30

Explanation:

Total number of golfers = 80

The percentage that qualified for the next round = 62.5% = 0.625

Number that qualified = 80 * 62.5%

= 80 * 0.625

Number of golfers that qualified = 50

Number of golfers that didn't qualify = Total number of golfers - Number of golfers that qualified

= 80 - 50

Number of golfers that didn't qualify = 30
