Question

Julia's text messaging plan costs $10 for the first 450 messages and 25¢ for each additional text message. If she owes $52.75 for text messaging in the month of October, how many text messages did she send that month?

Answer 1

$52.75-$10=$42.75

This is 450 txt msg

I'm assuming 25¢ is cents?

so 100¢=1$

1¢=1/100$

25¢=1/4$

42.75$/(1/4$)=171

total txt msg should be 450+171=621

Hope this helps!
