Donna worked for 13 hours each day for 6 days. Then the next day she worked 7 hours. How many hours did Donna work in all?

85 hours

Step-by-step explanation:

Multiply 13 by 6 to know how much she worked in those 6 days and then add 7 more hours to that and you should get 85 hours in total.

85 hours

Step-by-step explanation:

Donna worked for 13 hours every day for 6 days:

This means that she worked 13 hours each day so what we have to do is this:

13·6 = 78   < That is the amount of hours she worked for 6 days

Now we have to figure the last day:

Donna worked 7 hours.

This part is simple, all we have to do is add 78 from our previous equation and add it to 7 hours which gives us a total of 85 hours!

Hope this helps :)
