Given the statement:
In a group of 75 fourth graders, 20% do not like hot chocolate.
Determine how many students like hot chocolate.
Solution:
in order to determine the number of students that likes hot chocolate, we simply must know what percentage of the students like hot chocolate. To do so we subtract 20% to 100%.
Students who like hot chocolate = 100% - 20%
Students who like hot chocolate = 80%
Now we need to take 80% of 75 by multiplying it with the decimal value of 80%. In converting a percentage into decimal, divide the percentage by 100, hence in converting a decimal to percentage, multiply the percentage by 100.
= 80/100
= 0.8
= (0.8)(75)
= 60
Final answer:
60 students like hot chocolate.
