Question 1198255

The doctor has challenged Mr. Jonas, who weighs 240lbs to achieve his ideal body weight of 186 lb by losing no more than 3 lb/week.  How many weeks will it take for Mr. Jonas to achieve his ideal weight following his doctor's orders?
<pre>Let number of weeks for her to lose the weight, be W
Then we get: {{{matrix(4,1, 240 - 186 <= 3W, 54 <= 3W, 54/3 <= W, 18 <= W)}}}
Therefore,<font color = red><font size = 4><b> number of weeks for her to lose weight, or W ≥ 18.</font></font></b>
