Do you like to do sales reports?
Yes. I like numbers and math.
I like math, but I'm not very good at it.
When I do sales reports, I get confused.
My reports are easy. My boss wants our average daily sales.
So I divide the months total sales by the number of days in the month.
I can do that. But I have trouble with percents.
Then let's practice. Here, I'll give you some problems.
-->Conversation B
Here's the first one. Mary looked at 30 pairs of gloves.
She didn't like the color of 80 percent of them.
She bought all the others.
How many pairs of gloves did she buy?
Here's another one.
Kevin goes to bed at 11:00 15 percent of the time.
How many nights a week does he go to bed at 11:00?
-->Conversation C
Uh, I can't solve these.
Sure you can.
Ok, for the first problem. you tak 80 percent of 30.
Yes. 30 times 0.8 equals 24.
Then 30 minus 24 is...
Six. Mary bought six pairs of gloves.
Right!
Now, there are seven nights in a week.
15 percent of seven is about 1.
Kevin goes to bed at 11:00 one night a week.
You got it.
I just wish sales reports were this easy.
