A concert hall sets aside 17.5% of its 320 seats for a community group. Enter the number of seats set aside.
Respuesta correcta
56
Explicación
Using mental anchors, 10% of 320 is 32, 5% is 16, and 2.5% is 8; 32 + 16 + 8 = 56 seats. Adding 17.5 directly to 320 would mix a percentage with a seat count.
