William sold juice boxes at soccer practice. On which two days did he sell the least?
We’re looking at tallies. We see that one vertical line is equal to one. So in this case, it will be one juice box. And when we actually have four vertical lines and then one diagonal line, this is equal to five. Okay, so let’s see how many juice boxes were sold at each day.
On Monday, it’s one box. Tuesday, it was also one box. On Wednesday, it was nine boxes because we have five and four. On Thursday, it’s eight boxes. Again, we got five and three. And on Friday, it was five boxes.
So now, if we get back to the question, it says on which two days did he sell the least. So then, we can see that actually the two lowest values are one. And that’s both for Monday and Tuesday.
So therefore, we can say that William sold the least juice on Monday and Tuesday.
