At TelePower Plus, long-distance phone calls to China cost $0.59 for the first minute and $0.25 for each additional minute, plus an additional roaming charge of $2.50. If the total charge of a call to Beijing was $11.84, how many minutes did the call last?

Question

anonymous · Answer

$$.59+250=3.09$$ is the flat fee
then if you call the amount of minutes $x$ the total price was 
$$3.09+.25x$$ which you know is $11.84$ so you can solve 
$$3.09+.25x=11.84$$ for $x$

anonymous · Answer

may be easier to multiply both sides by $100$ and solve $$309+25x=1184$$ with no decimals
