222 - 198 = 24 pounds lost in 6 months
24/6 = 4, so Joe is losing weight at a rate of 4 pounds per month.
...in approximately how many months will he weigh 180 pounds?
A simple approach is to just list the weights.
Now: 198 lbs
In 1 month: 194 lbs
In 2 months: 190 lbs
In 3 months: 186 lbs
In 4 months: 182 lbs
In 5 months: 178 lbs
Since 180 pounds is halfway between 182 and 178, the correct answer must be 4.5 months.
Answer: D
