Question

Nova receives a bill for her cell phone each month. She pays a flat fee of $35 plus $0.05 per text message. This month, her bill without taxes was $51.50. Which equation gives the number of text messages, t, she sent this month?

Answer 1

35+0.05⋅t=51.50

Answer 2

total= $51.50
text fee= $0.05 per text
monthly flat fee= $35
t= # texts

51.50= 35 + 0.05t
subtract 35 from both sides

16.50= 0.05t
divide both sides by 0.05

330= t

CHECK:
51.50= 35 + 0.05(330)
51.50= 35 + 16.50
51.50= 51.50

ANSWER:
Equation: 51.50= 35 + 0.05t
t= 330 texts

Hope this helps! :)
