Question

Vishal's phone plan costs $45.37 per month plus $0.60 per text message. How many text messages can he send and keep his monthly costs to no more than $79

Answer 1

56 messages.

Explanation:

So, from the $79 you subtract $45.37, which results in $33.63. That is the amount he has left for the text messages. So, you divide $33.63 by 0.60c, which results in 56.05. However, you cannot have a .05 of a text message, so it rounds to 56 messages.
