There are 60 tables in a restaurant, with 25% of them seating 2 people. the tables remaining seat 4 people. how many seats are there in the restaurant?

Find how many seat 2 people
25% of 60=1/4 times 60=15 tables for 2

the rest seat 4
60-15=45

total number seats=15 times 2+45 times 4
totl number=30+180
total=210

210 seats

There are 25% of 60 = 0.25*60 = 15 tables with seating for 2 people. So there are 60 - 15 = 45 tables that can seat 4 people.

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.

The graph isn’t that clear
