Answer:
d 150 - 1.5w = 200 - 2.5w
Step-by-step explanation:
To write an expression for this problem, we call:
[tex]w[/tex] = number of weeks
Roy weighs 150 pounds at the beginning, and he plans to lose 1.5 pounds per week; this means that his weight after w weeks is
[tex]R=150-1.5 w[/tex]
Luis weighs 200 pounds at the beginning, and his weight decreases by 2.5 pounds per week, so the expression for his weight after w weeks is
[tex]L=200-2.5w[/tex]
Roy and Luis have the same weight when
[tex]R=L[/tex]
Therefore,
[tex]150-1.5w=200-2.5w[/tex]
Which is option D.
