The average money spent on cigarettes is 2,190 a year. If a 16 year old starts smoking and quits at 30, how much money will be spent during that time?

30,660

Step-by-step explanation:

The first thing you want to do is find how long they've been smoking. To do this, you want to subtract 16 from 30 (30 - 16) to get a difference of 14 years. Now that you know how long they have been smoking, you can look at how much they spend. If they spend 2,190 a year, and they've been smoking for fourteen years, you can multiply 2,190 by 14 (2190 x 14) to get a sum of 30,660.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
