Problema Solution
Bill, John, and Tim together missed 28 problems on the exercise. John missed 4 less than Bill and Tim missed 6 mor than John. How many did each miss? What is the equation?
Answer provided by our tutors
let
b = the number of problems Bill missed
j = the number of problems John missed
t = the number of problems Tim missed
Bill, John, and Tim together missed 28 problems on the exercise
b + j + t = 28
John missed 4 less than Bill
j = b - 4
Tim missed 6 more than John
t = 6 + j
by solving the system of equations
b + j + t = 28
j = b - 4
t = 6 + j
we find
b = 10 problems
j = 6 problems
t = 12 problems
