It could mean you have a contract that you can't break. Example: if you signed to Verizon for a year and wanted to switch to AT&T, Verizon could say "You're locked in with us for the rest of the year", so you would still have to pay for the rest of that year.

I did explain it, Mary. We already know that you have a 70 and 100. There has to be at least 82's since it's the mode (occurs the most). We can then solve for the missing number. (70+82+82+100+x)/5=76..x will be the last missing number.
