In max’s tea shop there is 25 percent (%) of caffeinated tea of the total number of tea present in his shop, in fraction form it 1/4.
Max's tea shop served all teas = 88
Max's tea shop served caffeinated tea = 22
Here we have to find the percentage of caffeinated tea with the overall tea his tea shop has, make the fraction value of the given number then after finding the fraction then multiply it by 100
According to the question
Percentage = number of caffeinated tea/total number of tea * 100
Percentage = 22/88 * 100
Percentage = 2/8 * 100
Percentage = 1 / 4 * 100
Percentage = 25 %
Therefore in max’s tea shop there 25% of caffeinated tea.

You already got the first two questions right: the group with the highest number of people unemployed / unemployment rate is the one with the highest bar in the respective histogram.
The two graph are related in this sense: take the first age group as reference. We know that 700 people from 16 to 19 are unemployed, and that those people represent 14% of the population, then we know that the 14% of the population between 16 and 19 is 700.
We can deduce that, if x is the number of people between 16 and 19, we have
So, by the relation between the two graphs, we can deduce the total population for each age group.
