Problema Solution
Lou, Tami, Del and Sheryl score 78 points total. They score a consecutive number of points from smallest to greatest in respect to the order of their names above. How many points did Lou score?
Answer provided by our tutors
lou = x points
tami = x + 1 points
del = x + 2 points
sheryl = x + 3 points
total = 78
x + x + 1 + x + 2 + x + 3 = 78
4x + 6 = 78
4x = 72
x = 18
so lou scored 18 points
