### Instruction: The table shows the number of days per week households eat their dinner together.  What percent of households eat their dinner together at least once a week? \begin{tabular}{|c|c|}
\multicolumn{2}{c}{}\\\hline
7 days&40\%\\\hline
5-6 days&30\%\\\hline
1-4 days&20\%\\\hline
0 days&10\%\\\hline
\end{tabular}.### Response: I want to find the percent of households that eat their dinner together at least once a week, so I need to add up the percents of households that eat their dinner together 1 or more days a week.
That means I need to add up the percents of households that eat their dinner together 7 days, 5-6 days, and 1-4 days a week.
Adding up those percents, I get 40% + 30% + 20% = 90%.
So 90% of households eat their dinner together at least once a week.
