a Draw a Venn diagram to show this information. looks simple enough,
draw your Venn diagram, label the intersecting circles sw, s and f
place 5 at the intersection of the 3 circles.
Now look at the intersection of the sandwich and the fruit, it says 7
but you have already placed 5 in part of this region, which leaves 2 for the part of sw and f but not f
continue in this pattern until all regions are filled
Their total should be 30 Students | food
