Answer:

7 months

Step-by-step explanation:

An equation which gives us J's weight after any particular month is

W(m) = 180 lb - (5 lb/mo)t

Her goal weight is 145 lb.

Therefore, write:

W(m) = 145 lb = 180 lb - (5 lb/mo)t.

We must solve this equation.  To do so, subtract 180 lb from both sides of the equation:

145 lb - 180 lb =  - (5 lb/mo)t

-35 lb =  - (5 lb/mo)t

t = 35 lb   /   (5lb/mo) =  7 mo

J. must diet for 7 months to get her weight down to 145 lb from 180 lb.
