Problema Solution
Solve by using the five steps for problem solving. If there is 8500 students and there is one third as many over the age of 25 than under 25 how many are over the age of 25?
Answer provided by our tutors
Step one: form an equation
1/3 x + x= 8500
x=6375
1/3 x= 2125
Checking work: 1/3 x+x=8500
2125 + 6375 = 8500
x is the number of students 25 and under.
1/3 x is the number of students older than 25.
