Alright, so a food truck owner samples 100 people on two separate days. There are our totals in the graph. The question is asking for how many burgers will the food truck sell, so try to focus only on the burgers, not the other food items.
On day 1, 33 people liked burgers.
On day 2, 42 people liked burgers.
33/100, and 42/100.
75 people out of 200 like burgers.
In the second part, its saying we should use 900, in place of the 200. So, what we do is divide 900 by 200, to see what we should multiply 75 by. Remember: Whatever you do to the top, you have to do to the bottom.
We get 4.5. So, 75*4.5=337.5
It's asking for a whole number, so we'd use 338. We round up because it is a .5, not a .4.
So, based on the samples, about how many burgers will the food truck sell?
338.
