Question

Kim scored the least number of points. Claire scored five more points than Kim. Sam scored twice as many points as Kim. Together the three students scored 85 points. How many points did each student score?

Answer 1

c= k+5
s= 2k
k+s+c=85

Use substitution to find the value of k
k+ (2k)+ (k+5)= 85
4k+5=85
4k=80
k=20

Plug in the value of k to find the other values
c=k+5
c=(20)+5
c=25

s=2k
s=2(20)
s=40

Final answer: Kim-20, Claire-25, Sam-40
