Question

the cellular phone plan you signed up for gives 400 minutes a month for $35 and charges $.15 for each additional minute over 400 how long can you talk on the phone but stay within a budget of $45

Answer 1

I think 514.30

if you divide the 400 by the 35 you get a big number (11.42857142857143) and if you multiply that by 45 you get 514.28 (and a few other numbers). If you round it you get 514.30.
