Eric invited 200 of his friends to his graduation party. 75% of those invited said yes. 15% said no. The rest said maybe. 10% of those that said yes did not turn-up. Half of those that said maybe managed to attend anyway. How many friends attended the party?

Respuesta :

Answer:

145

Step-by-step explanation:

75% of 200 = 150

75% + 15% = 90%

100% - 90% = 10%

10% of 200 = 20

10% of 150 = 15

150 + 15  - 20 = 145

145 friends attended the party.
