Respuesta :

7 because if you multiply 48.6 times 0.15 then you would have 7.29 but you have to round down because there’s no half a button

Answer: 324 buttons

Step-by-step explanation:

1 button in 0.15 seconds = x buttons in 48.6 second d

1 / 0.15 = x / 48.6 (cross multiplication )

48.6/0.15 = 324
