51.50 + 0.05x + 35.35   
(x being the amount she sent)

Nova pays a flat fee of $35.35. She pays $0.05 per text message.

Her bill was $51.50

first subtract the flat fee from the total amount

51.50 - 35.35 = 16.15

Then divide 0.05 from 16.15

16.15/0.05 = 323

Nova sent 323 text messages.

hope this helps
