The equation that's been computed shows that the number of cell phones that his family can have will be 2.
How to solve the equation
From the question, it was stated that the cell phone company charges $50 plus $40 per line each month and that Luke must spend under $170 on his family's cell phone bill each month.
Let the number of cell phones that can be bought be represented by x.
The equation to solve the question will be:
50 + 40(x) < 170
50 + 40x < 170
Collect like terms
40x < 170 - 50
40x < 120
x < 120/40
x < 3
Therefore, the number of cell phones has to be less than 3. Hence, this will be 2.
